Ridiculous. Utterly ridiculous. I just called and attempted to place an order by telephone. I was promptly asked to call back in 45 minutes! What kind of business asks a potential customer to call back??! I apologized for bothering them and informed them that I wouldn't be giving them my business. Sorry about it.
