3" is the smallest one I have, and I have never seen any CLs in Petsmarts/Petcos around here. Keep in mind that Ohio prices are also pretty expensive compared to other places. Try to find any cheaper sales in the buy/sell forum, there's not many. Most people on here would rather buy slightly more expensive, but raised by an actual fishkeeper, loaches than ich-ridden faded loaches at Petsmart.
EDIT: Okay, really?
The CLs are lower than you'll find around here, the tiger loaches are cheaper than I bought them for, the congo tetras are average-priced, the del is easily the cheapest you'll find anywhere in Ohio, the creni is dirt cheap, the bulbs and heater are both well below sale price, and the moke is currently only being sold in the US by 2-3 vendors, so the high price is justified. I'm also entertaining trades. If you don't like the prices, fine. But please stay out of my thread.
