I just did a quick test and searched for the FF7 soundtrack on eBay (Germany). The only offers that look legit to me are priced at 55 EUR (or higher). The rest comes from Hong Kong (and therefore is most likely a bootleg) or doesn't mention the catalog number (another bootleg indicator).
OK, there is one copy for 35 EUR (from an US seller), which at least mentions the correct distributor (Sony). This is all in EUR though and without shipping.
Official prints are expensive. And I wouldn't part with my Alter code:F copy for just 20 bucks. I wouldn't part with any Naruke soundtrack in the place, but that's a different story

I've bought the original Wild Arms OST, the FF13 one, FF8, FF7, Crisis Core, FF7 Piano Collections, and the FF8 Piano Collections from this seller. And they're all legitimate copies, brand new. Check out their store and see what they've got. Some really good OSTs on the cheap.
I also told the guy with the Alter Code F OST that I'd hit him back up when I got the spare cash on hand. Normally I wouldn't have any issue forking out $30 for an awesome soundtrack. My vehicle just keeps having issue after issue. Radiator busting, distributor going bad, thermostat dying, and now the catalytic converter is screwed up. So I'm just a bit short on cash these days.
