Will the product page's price change to reflect the price after coupon?
Looking into that as well. The (somewhat) problem is that like most things, it's like Valve made it almost intentionally difficult. Rather than listing the AppIDs for the items coupons can be used on, they have YET ANOTHER ID that ties into the search results.
So the way it works right now is this: you browse to Steam, and Enhanced Steam grabs your coupon IDs, finds the search ID for that coupon, then uses that to load the search results to find the correct App ID for each coupon.
It's needlessly complicated and could be easily fixed if Valve would simply put the Steam App IDs for the applicable titles into their coupon data feed.
SO I'm hoping that I'll be able to pull this data and update the page appropriately with the correct discount, but to do so will require that I essentially do the above steps in reverse.
EDIT: Got it!
