How do you prevent or limit re-sellers

We understand that in the age of eBay and the likes, certain people buy up games and resell them at a higher price claiming rarity when a lot of times this isn’t the case. To combat this, we have placed a limit of two (2) copies per customer, per address (billing and shipping) on all games. If we detect that more than two copies of a game are being sent to the same address or customer, we will cancel your order and refund your money. You will have to go through the ordering process again, following these rules. If a customer is caught doing this more than once, they may be temporary or permanently banned from using the store. In rare cases, a limit of 1 copy per customer or address may also be imposed. Those will be clearly marked in the items listing.
