CardSwap is disrupting the gift card phenomenon by allowing members to sell their cards at decent discounts to other members. Somewhat similar to eBay, CardSwap acts as an intermediary, and takes a 6% commission on each transaction.
The advantage to the seller for using CardSwap is that they end up getting cash for something that they got for free, while the purchaser ultimately gets a discount on something they were going to buy regardless.
Implications - Personally, I find this site ingenious. For years I've contemplated how useful a service like this would be, and now CardSwap has established itself as the preeminent online Canadian marketplace for gift card swaps. Strap in.
