If you think it's bad enough in the States, try north of the border...
A few suppliers will carry more than just Tropica, but unless a store / website has dedicated hobbyests supplying them, it's a copy and paste tropica flyer with maybe a handful of other species from 1 other supplier.
Extremely frustrating, and same as above, I do not want to have to order from 3 vendors and pay $$$$ shipping on all 3 to get what I would like.
Side note - FINALLY I have access to a few very good local fish stores, after waiting 10+ years. The only problem is the best of them only carry Tropica and inflate the heck out of the price, the others at least have other suppliers and are cheaper, but quality isn't as nice.
