The prices in store are usually within 5bucks of the online price, and if you show the cashier it's cheaper online they SHOULD reduce the price
They're the same as kritter keepers, sturdy enough for a small hob and you can put in a heater and stones and all, the large is a good betta home just make sure to be careful not to scratch the acrylic (some people complain about scratching up the acrylic tanks as opposed to glass, I've only ever had 1 scratch in 3 acrylic tanks, just be careful.

 

I had to pay 8 extra dollars for a heater I bought there over the online price. They wouldn't match it despite looking at the online price themselves.

I suppose it might vary from store to store depending on the particular manager at the time.

 

In the past, I have used Pet Keepers for bettas. They are pretty sturdy, but, as previously mentioned, definitely scratch easily. I wouldn't recommend using anything smaller than the "large" size for a betta, though.

Honestly, knowing what I know now, I would skip the Pet Keeper and instead buy an open-top, glass 5.5 gallon aquarium at PetCo. The price for the 5.5 gallon and the large Pet Keeper are almost exactly the same, but (imo) the larger glass tank is a far superior choice for a betta. You can use cling wrap for a lid until you can buy a permanent one (full hood or glass canopy). The same filter and heater would work in either tank, so why not go for the bigger one?

 

There is an X-Large Kritter Keeper on eBay (about seven gallons) for around $20.00 which includes shipping.

You could buy these and stick them to the inside of the hood for lights. The seller is really nice and if you tell him what you need I'm sure he'll work with you.

I have two large Pet Keepers - one for each of my bettas (they're about 3 gallons I think). I like them, personally. I have heaters and filters in both of mine, as well as substrate, plants, and hide-outs.

 

My female betta (Lady Iris) home is a pet keeper(large). It is a good size for bettas.
It is heated, filtered, and cycled. It is study, she has been living in it for 7 months. It does scratch easily, so be careful with water changes. They are budget friendly.
The store should price match. Good luck.
