The regs are pretty standard, but happen to be the things you are most interested in (so that stinks). However, it just isn't logical to expect a retail store to sell something at such deep discount that they loose money on your order... that's just not a good business plan.
just for fun,
things that would qualify for free shipping
filters
filter media
filter pads
fish food
test kits
water conditioners
buffers
nets
fish food
light bulbs
backgrounds
aquarium cleaning supplies
books (but who reads anymore LOL)
dog toys
food bowls
heaters
desktop aquariums
chicken coops
and many other things
so they havn't eliminated just about everything, just the things that would cost the most to ship.
