I had some old games I wasn't playing anymore so I took them to Game Stop to trade them in. They only offered me $13 in store credit! I said screw that, I'd rather keep them. Later on someone told me to try Gator Byte. I had never heard of them before but figured it was worth checking out. They offered me $30 cash or $40 store credit for the same games! The games they sell are mostly cheaper as well, they've got my business from now on!
I had viruses on my computer - they are very quick and reasonable in their prices unlike some stores that I had used before who sat on my computer for weeks. They returned my computer the same day I brought it in and never made me feel like I was stupid when I didn't know what was wrong with my computer. I will always go back to Gator Byte.
