Double-Sided Tape
You can get 130 inches of this tape at the dollar store at a way cheaper price. It is shorter tape than the 450-inch role sold at Staples for $4.70, but its still 1/5 cent cheaper per inch!
Cotton Swabs
Why waste your money on cotton swabs from CVS when you get the same product at the dollar store! At CVS a box 170 swabs are sold for $2.79, now that is just stealing your money. Maybe it is not the actual Q-tips brand, but there are subtle differences.
