When I bought in 1993, the minimum purchase was 230 points as I recall. We started with 240 points and quickly added on another 30 points would have ensured us a 2 bdrm exchange through II if we wanted. After moving to FL, I added on a few more at OKW and then another 160 at Vero Beach (love Vero, and bought enough for a couple of nights in a Beach Cottage in summer, but OUCH, those maintenance fees!). All told, I have just under 500 points and LOVE, LOVE my membership. It has allowed us to do things we never could have done without it.
