The shipping costs seem to be high, but I distinctly remember reading about a great deal for TY CD-R 48x discs in this Forum a few months back and ordered a stack of 100 from the company in the U.S. (I'm in Canada). The price for the CDs was great.... but the shipping cost was staggering. They only would ship via UPS, so in addition to their balloon shipping cost, I would have had to pay an additional $25 "Brokerage Fee" to UPS on top of the regular shipping cost. All total, the shipping would have cost me $60+ Canadian. Needless to say, I immediately got on the phone and canceled the order. The salesperson was sympathetic and gladly complied with my cancellation request.
You have discovered what I found out some years ago. FedEx is somewhat better as they did not add a "brokerage fee" but the standard 25$US shipping cost makes one think twice about the "deal"!
Over 10 years ago, I had found a deal on a Panasonic dot matrix printer from some discount warehouse in the N.Y. area. When asked about shipping method. I requested by land. They sent it by plane and had to pay around 125$CA and picked it up myself at the airport to keep costs down. They had charged my credit card and never accepted to correct the shipping fees... I spent hours on the phone to contact the cc company and said they couldn't do anything as it was a foreign purchase. Nowadays, I try to keep my purchases within Canada although, when in the USA, I try to grab the deals at BestBuy/BestBrands etc.
