Hi, Just wondering how to do the math for a 'Buy Multiple' button (x1, x10, x25 etc) but the price increases with each one you buy.
In this case it looks like this:
1st one Costs $10, 2nd Costs $21, 3rd Costs $44 etc.. With an increase of floor(cost*2.1).
The problem I'm having is that, for example, if I click buy x10, the cost will be $1000 instead of (I believe) $15018.
Hope this makes sense. Thanks.
