How is this a deal when every 2 or 3 months they go on sale for this price?

Also the OP got the description wrong. These are NOT compatible with the iO series electric toothbrush models. The product details on the Costco page says this:
The Oral-B Floss Action X brush heads are compatible with Oral-B rechargeable toothbrushes, except for Oral-B iO Toothbrushes.

I prefer these floss action heads but I have not seen them in my warehouse for the past year. The cross action ones without the yellow floss things on them are always available.

Just because a sale repeats itself, every 3 months, it doesn't mean it's not a sale.

It does not repeat for the FLOSS ACTION though.

Are these notably different from the Cross Action Pro heads? For example these are only $3.35 each (vs. $4.40 each from Costco): https://www.amazon.com/clp/B0CCJQW69X
