I am used to my local Pet Co prices on fish. Typically they are running sales where platies are around a buck and guppies $2. When I visit some other local stores they are a minimum 25% or more expensive than Pet Co's regular prices. my last purchase, Kulie loches, at Pet Co were $2 each, regular price. Other local pet stores were $5 to $7 each. Pet Co did not sell me that Loach for a loss. Makes me wonder what the mark up on fish really is? how can Pet Co be so more competitive?
