After several email exchanges, I’ve been refunded the $6.93 and $3.10 from ASI Order and VMWare, respectively for the sales tax they collected on my completely electronic downloads (the first for the marathon pictures I ordered and the second for a copy of VMWare Fusion). This is a small victory for me, but I feel that these companies need to get with the 20th century and look at the tax laws for electronic commerce. ASI Orders appears to still be charging sales tax on their website, so I suspect they refunded my money on the sales tax to get me to be quiet.
