I believe this site is a complete scam (will update if I receive payment). I sent them 50 calculators worth over $950 on behalf of my employer (a local high school) and they have not submitted a payment. They responded saying they received the calculators and were 'processing them' but weeks later I have not received payment. They don't answer the phone, nor respond to order inquiries, but do respond to questions about selling a calculator (though they gave me the runaround again when I asked about my shipment). Attemps at email have been futile. I am now going to the BBB, State Attorney General, IC3, FTC... STAY AWAY FROM THIS SITE! Wish I had read the reviews beforehand.
