Taking advantage of Gamestop's Trade-in Policy

WAIT! Before you read this any longer, I want to say I posted this to help people, so please don't ban me for advertising my YouTube video that explains it in detail

Listen up people, today I struck a pretty good bargain at GameStop/EB Games. I price-matched Shape Up (X1) for 9.99$ at Toys R Us and sold it back to Gamestop for 17$.
Since they gave 30% more when buying Infinity stuff, I got 22.10$ in store credit for only 11.49$ spent. I bought the Tomorrowland Power Disc pack (9.99$) and the Minnie figure (14.99$).
After all, it cost me 13.90$ to get Minnie and Tomorrowland, who are worth 25$.

I created a youtube video to explain it in detail: https://www.youtube.com/watch?v=jX0jdgw5fnU

Thank you for reading and I hope you get many Infinity figures for cheap!

Nothing dodgy about it really...just retail. If you shop at GAME in the UK and are within 1 mile of a CEX you can price match and get £1.00 difference. This can really add up if trading in lots of games.

Never said it's dodgy, yet I published it because few people seems to know about price matching.
