I get horse feed, bedding, dewormer, and Jack's food from TSC.
I get Sally's food, the cats' food, and some treats and toys at Pet Supplies Plus.
I get other treats and toys from Petsmart, and bought my recently acquired betta's tank, heater, and gravel from there.
We got our betta and his food at a local pet and hobby place--their bettas looked the cleanest and healthiest by far.
We occasionally buy toys are Big R's.
I go to another feed store for my horse's joint supplements.
We occasionally go to Petco for some socialization and to buy whatever looks good there.
We get kitty litter where ever it's cheapest....
