I hope you and you wife get some help so the society at large doesn't have to keep suffering. Did you not see the very clear and large picture when you bought it?

Fickle demanding neuroticism must be costing our nation billions in lost productivity and waste.

Society shames people that dare use a plastic bag or driving and here you are seeming proud that you bought something you could see pictures of, to only to turn send it back it. Your whim has large costs and impacts. It dragged in thousands of people that had to make it, supply, transport and deliver the product to your door for you to say nevermind I have psychological quirk that makes me not want it now.

Couldn't you just have gave them away or something? believe me I am not some environmental scold but at the human and societal level common courtesy and sense should dissuade us from doing stuff like that.

It does raise prices, creates much waste and wasted energy and effort for everybody. Just calculate what you cost your community to have to have the post office come to your house with the item and then come back and take it away, That and all extra costs you created with your change of mind are large and are likely in the thousands. If you opened them they may go back to Amazon and then to a landfill. No I do not worry that we are filling up the landfill it just is wasteful.

I'd advise that on low dollar items like this even if not thrilled keep and find some way to use it or give them to a friend or charity.

They weird at times but just in case.
It goes in in the payment methods section of checkout.
  1. Open the payment methods section on the left by clicking "change".
  2. It will open and drop down, scroll down to where you enter gift cards or promo codes
  3. Plug code in there and click apply(Should see green text message right under the box saying it took).
  4. NOTE: Price at top right will not change till you finish out by clicking the "Use this payment method" that is above the box showing the price.
If it worked the price will then drop.That last step and the price not changing till the end has caused confusion.

I think its a new distinction between prime student and prime at full price? Just tried again, switching payment option from gift card balance to a card and got the same "The promotional code you entered cannot be applied to your purchase." rebuff.

I have both this Coslus and the Bitvae China made flossers and they have been great so far. My Bitvae has been going strong for fourteen months now and the wife Coslus is doing the same at the six month point. I replaced my plug in Waterpik..I did at one time have a China made Waterpik branded travel flosser like this but it only lasted months before failing. Both the Bitvae and Coslus are better machines by far than that was.

If anyone is looking and cant get this deal add a deal alert for both this and Bitvae that both show up at this price point with the codes with some regularity.

If anyone is not water flossing do not hesitate to begin especially at these prices. It will really help with long term dental health and can save you much pain and possible tens of thousands of dollars. I know this from personal experience and I am 100% sure if i would have started water flossing earlier it would have saved me much grief and money.

When young and strong I did see water flossers and was interested but cost would always get me dissuaded and thinking it was maybe not really needed. I paid a high price in the long run for thinking like that. At $10 it should be a no brainer. Even if it lasts a year and gets you in the long term habit of water flossing it is a tremendous win.

Do note that for this and the Bitvae you may see many comments and members and trash the deal and product. Take that with grain of salt as most is driven by members dislike of SDs promoted deals policy. Yes this is promoted and SD make some commission or percentage doing so but that does not equate to it being a bad product yet many members will try to convince you that that is true without having ever used or tried the product.

Thanks! That may be true but the codes can still be confusing and fickle.

I initially had black in my cart and it did get it apply for the price of $10. I did not checkout fully as I was jumping back here and for a short period I could get it to apply again. I just left the cart and then went back and it applied for the black again and I just ordered.

It is not unusual for them to be unusual.

it applied to every color I tried making them $9.99 not just black and green. The subtotal discount it gives displayed in cart is calculated all weirdly individually tho coz it says my white one is over $8 and my purple and green are over $10...but total is correct, I bought 3 and displayed total was $29.97 so it is $9.99 each when divided by 3

hmmm, no consistent reason based on data points above. Happy the green worked for me. Black still erroring out despite many attempts.

I had to select Prime Day delivery to get the $10 off. But when I added an additional item, it didn't seem I had to select Prime Day. Bought 2 and another thing. Still did Prime Day to get my 6% back. Yes sir, that's an additional $0.25 back. Hope they're worth it, but it's only $20.

Code works for me, I just ordered one! Make sure you are using promo code BMJSI6QP and not COSLUS as I did the first time
