Placed a tax exempt order on line, submitted tax exempt paperwork via electronic upload. Got email from Academic Superstore that eligibility had been approved and order was being processed. When i got my monthly statement they had charged me tax. Called to get corrected and had to resubmit paperwork all over again (this time via fax and no 800 number). If this is any inidcation of how they run the company, you should be worried about your order. Find someone else to buy from, even if you have to pay more-it's worth it! They used to be very good about both ordering and service, but lately, they just are not worth the hassles anymore. This isn't the first problem I've had with them either.
