So I found a supplier and am negotiating prices right now but it will be a minimum order of 18x rw4, 24x rw8, 16x rw15, and 16x rw20. Min is per type so if min rw4 can be ordered that can complete the order. Cannot be spread between models as is not 8x 4 and 16x 8 etc. So far looking like prices will be at least $10 cheaper than cheapest price I have found online and no shipping.
