My husband recently retired from his job of almost 30 years. He discovered that he could work as little as 10 hours (one day) a week at a very popular large national chain hardware store and get the employee discount of 10%-30%, depending on the item purchased.
Being farmers and having some rental units, this is wonderful. He only earns around $100 a week before taxes, but after only 4 weeks, he has saved us in discounts over $900 in purchases for a home we are reroofing, air compressor, paint, carpet, and farming/fencing supplies.
I mentioned this to another retired friend of ours, and she informed me that is why she works 1 day a week at a nearby restaurant. She gets a 50% discount on meals for her and her family. As a result, they eat there 2-3 times a week.
