I generally trade, especially when the people I work with start harvesting from their garden. I DO NOT have a green thumb so I trade for home grown tomatoes, cucumber, green beens, sweet peas etc.
One co-worker's husband works for a company that makes laundry, dish detergent and hand soap. He gets these items for next to nothing or free when they have overrns, so my co worker gets free eggs and I have not bought the above mentioned items in two years.
One neighbor works for a hotel chain in their marketing department so when I go on my yearly vacation she gets me a SWEET DEAL on my hotel room. Trust me, the trade is heavily weighted to my side, she only takes a dozen eggs about every other week.
