I had several experiences where sellers provided different information in their description than they did in their title or listing details. If the information in the description is there for clarification because the listing details fields didn’t give the seller the ability to add complete information, then I believe there is no seller foul. But if the product description has contrary or misleading information that is substantially different that what was in high level listing details, then I believe the seller is at fault.
As always, it is best to read the whole listing, including the description, and ask questions to the seller if there is any confusion. If the description seems clear, but conflicts with what is expressed in the listing details I would advise not to make the purchase.
I know this is hard to do at times, when rare items become available or coupon codes are ready to expire. So, if you purchase because there is some sense of urgency, just don’t redeem the item until the seller gets back with clarifying information or corrections. I believe GameFlip would be supportive of the buyer if the seller provided false or misleading information and then refused to take the unused item back for a refund. If the item is already redeemed by the buyer and the seller has a convincing argument as to why they listed the item that way, it is more challenging to get a fair settlement. Because GameFlip has no way to facilitate partial refunds, there is no straightforward way to find a middle ground.
In the case where the seller is breaking the GameFlip rules (e.g. by selling an item that requires a VPN to use) then the buyer shouldn’t lose the dispute, because the item was never allowed.
