This is the only US based store I've found to be priced competitively with China based stores. You can't beat great NDS accessories at a great price shipped fast. Thanks simplymods.com

Great selection of products and really good prices as well. Easily navigable site to find what you need.

first of all, this store is located in US, and their price is competitive to those located in china! you can buy ds flash cards (they have other things as well.) for cheaps, and receive them within few days! compared to 2~3 weeks shipping from china, this is incredible!

Here is an american seller of the ndsflashcards the price are quite reasonable and will come fast as they offer first class and priority mail for reasonable rates and not overprice shipping charges like some american sellers.

I ordered an AceKard 2i from simplymods and it arrived very quickly. The microsd card and the AceKard 2i worked fine, but the microsd card reader didn't work. I let them know via e-mail and they sent out a new one. Unfortunately, the Post Office delivered the package but not the item. I let simplymods know and they sent complete replacement plus a high quality USB adapter for the microsd. This is honestly the best service I have received in any industry in years. I will definately purchase from them again.
