Found this by accident google Chrome was running slow flicking back and forth between IE 11 surfing Ebay I pasted the URL into chrome and got a higher price.
Chrome has Cashrewards app.

M6 x 25mm 50 pieces IE 11 price $14.75 AUD not logged in
m6 x 25mm 50 pieces Google Chrome price $15.53 AUD logged in
Took screen shots of both URL's the sellers not offering the discount on Chrome but offers it on IE 11 so sometimes you could be 3.7% better off not using Cash rewards by the looks of this.

Lol no… 1 of those has a 5% saving probably coz you already have it in cart, that's all.
There's a discount if you buy 2 or more you get 5% off. 1 of those pages is picking up on it
Maybe go have a coffee…
