I had a terrible experience with this website. I sent them two perfectly good TI-83+ calculators. Received nothing in the mail for a week. Called them. Got an answer, the guy was very helpful, said they were delayed, but check would be in the mail that day. Fine. Waited another week. Nothing. Called again. Same guy, same explanation, check is about to be put in the mail. I did this for a month.
You can see where this story is going. I never got my check. I eventually stopped calling because I realized it was a scam and I did not have any straightforward way of getting my money or calculators. The dollar amount was too low to be worth my time pursuing any sort of action. Please do not use this site: there is always a demand near the start of school semesters for graphic calculators.
