Well, Adobe prices are the same (I think) but in most stores, Mac is cheaper (usually but that always depends on how mean the shop owner is) , but the availability seems to be less common. But Macs are more expensive when you buy them, but you are paying for speed and convenience (Thank god for spell check). I bought mine off eBay, but I looked through a couple of shops first before realizing I had more important things to spend money on (Like Warcraft) and just went for eBay. My version works perfectly and it was hassle free buying it. The shops I looked in either had the Mac or PC version, not both, so it entirely depends on discounts and store prices. So there you are. A completely unconclusional, long, boring, stupid and pointless post about how some shops are cheaper than others.
