My local grocery co-op is established (been around for 50 years), with 3 locations, and is raising a few million to upgrade the square footage of their flagship store. They are offering a 4% annual dividend on money put in (limit of a $100k investment, I believe). The only stipulation, besides investment size, is that they require a 10-year term. Setting aside the (real) risk of the business going under, any other good reasons to avoid replacing some bond investments with this?
