I remember the polywad loaded "oldwhites" in #6 ,that became real scarce - the people that parted with those years ago , probably wished they had them back .
There were always WTB adds for them , for a few years people would post up they had a local corner store had this or that , and they would be shipped to another member - after some time it became hopeless to find any
You will see the same WTB threads for a years to come for whatever loads become discontinued this season or next , occasionally there might be a pallet of the stuff found here or there - I know money is tight with folks , but this might your last chance , so crack your wallets and buy up a little more if you use it --
