@katie12399love sorry, but this is a question to be adressed to that store. That store is part of the so-called grey market and EA doesn't have any direct contact with them (or otherwise).
You always take a risk buying from an unauthorized reseller, as the key might come from a stolen lot, bought with stolen credit cards and other shady operations.
This is the list of authorized EA resellers.

Any other should be either avoided or checked really well in advance. I can add quite a few sites to avoid, but i don't feel to make free publicity to those shady sites (just mentioning them it could generate enough publicity and they don't deserve that)
Best way to avoid scams is to buy directly from the Origin store. Support will help you if something goes wrong with the purchase. But if you buy from an unauthorized reseller, EA support can't help. Any problem will have to be adressed by that store.
