On the plus side, everything, including shipping, costs twice as much from them as it does buying from a reseller. 

The shipping costs are
not inflated, even the complaints posted here.
Blame the shipping company.
(The
one exception IIRC is when happs used a way too big box, upping
UPS's size charge even more. He got a refund, though.)
The main problems are happs doesn't precalculate the shipping costs so some people are surprised at how much UPS/FedEx charge, and more important resellers like DM charge less for the same products.
If DM shipped the same products on the same shipping company, he would charge the same amount. (Which AFAIK is why he prefect USPS & doesn't carry the huge item that causes the most shipping complaints of mame (coughbezelcough).)
Back to the OP, happs shipped within a couple days the few times I ordered direct. Are they out of stock?
