Buy from NDS-Card. They’re 100% legit, and they’re a sponsor of GBAtemp, meaning every purchase gives the temp a bit of money. And yes, it is a good, reliable source. I bought my flashcart from there. Their Pay-PAL method is more than a little sketchy, but it works. You will get your item - otherwise it’s a true mistake. Note: they are based in China so the English will be a bit weird and it’ll take long as hell to get to you (expect 1+ months), but it will come.
