Buying Shoes on Amazon

[Acer]

I have bought shoes there several times, and experienced the same wide price swings.

I pick out what I want, leave it in the cart (or the saved for later list) then wait for a few weeks while the price bounces around, consulting camelcamelcamel for a realistic range. When it hits my target, I hit buy.

I'm guessing the margin on shoes is massive so they can play these games and still come out ahead.
