Dyson V11 Outsize $679 through Dyson's Exclusive 20% Savings Event

Dyson.com has an Owner Rewards program that allows you to take 20% off select regular priced items. I myself am new to any Dyson products and when looking for a new vacuum I decided on a Dyson cordless vac and wanted one that I can swap a battery out if it died on me. Then looking at the price for this vaccum... that was a downer but found this 20% off deal. The way I did it was I called customer service and told them I was interested in the V11 Outsize and heard of a 20% off a regular priced item. I asked if this item qualified, so he looked it up and came back with a yes it qualifies and would throw in a floor dok for free. Price for me after tax came out to $679. I thought he was going to ask me for a serial number for one of my previously owned Dyson products to get this promo but he did no such thing. He just gave me the 20% off and I was happy.
Right after getting off the phone I thought to myself I should have done it online to use a cashback site. I found one offering 8% back and might be others offering more. If you decide to go the online route, I didn't see an option for adding the Floor Dok valued at $149.99 for free but you could add a Deep Clean Kit valued at $69.99 or Clean & Organize Kit valued at $74.99 for free. You will also need to own a Dyson product to get the 20% off. I think you plug in the serial number to get a one time code. I know the cashback site would have gotten me some $50+ back but the Floor Dok is nice and more expensive than the other two options, so I'm sticking with the way I purchased it. The vacuum itself has only been out a month or so and I sure wasn't paying full price for it and thought this might be a deal worth sharing if anyone really wanted a vacuum with easy interchangeable batteries.
