fuel surcharges are being added to just about everything. people have to be competitive on the fish, other stuff, but the one thing they cannot control is cost of fuel. most of the time that cost is covered by other charges and profit on the product. but with skyrocketing price of fuel, and more competitive markets, you cannot raise your prices so they add the fuel surcharge.
what i find funny though is i wanted to buy the 50 hermit crab shells, but they wouldn't ship them with the RO unit i wanted to buy because they don't meet the $70 minimum order for LIVE fish. last i checked, shells aren't alive...
