28. Shop on Alternating Half-Off Days
Every thrift store has a different day of the week where they offer half off deals. For example, in my local area, there is a 50% off sale happening almost every day of the week. Goodwill has their half off day on Sundays, The Salvation Army has it on Wednesday, and the privately owned thrift store is on Saturday. Obviously, this might change across state and city lines.
Also never assume that two Goodwill locations will have the same schedule. Few people actually realize that Goodwill is a franchise. This means that private business owners can open a Goodwill thrift store. Even though they have the corporate name on the sign, they are allowed to make their own policies about the sale schedule. So you could possibly go to the town next door, and it’s not going to be their 50% off day.
