Products that have the Market Cornered

I have a growing list of things that I will only buy one Brand of. Tonya is getting more than a little irritated by this, but here is the list so far:

Ketchup--Heinz

Cream Cheese--Philadelphia

Peanut Butter--Jiff

Dry Roasted Peanuts--Planters

Toilet Paper--Charmin

Mayonaise--Kraft

Computers--Apple
