I needed new eyeglasses. So, I went to the mall. Tried on a bunch of pairs. Found one pair of frames I really liked. Wrote down the SKU number. Went home. Looked it up online. Purchased it for half the store's retail price. If we keep doing this, the retail stores won't stay in business, and I won't be able to use this tactic. But, I'm stupid if I pay double for the same thing. So, what's the solution?
