I love science and this site claims to have all kinds of cool stuff. I ordered two elements (Potassium & Sodium) two months ago. Two weeks after I placed the order, I asked for status and was told "Backordered"... but nothing indicated it on the site. I gave them a month and asked for status, "Still not in"... but yet my credit card was charged the day after I placed the order... Three weeks ago I asked them to cancel it, no response. Two weeks ago I asked them again to cancel it, they said they are working on it. Today (2 months later) still not cancelled, no order received, and funds not returned - I had to file a claim with my credit card company to dispute the charge. Again, cool site - but they failed to deliver.
