One note on Major surplus,I ordered a set of used like new British lite weight DPM last october.They charged my credit card immediately.After it did not arrive in 2 weeks I called them and they said it was on backorder, would be in stock in 2 weeks.
It pissed me off that they would go ahead and bill my CC when it was on backorder.But the price was so good(I think $14.95) for a complete set I told them to continue with the order.So about once a month I would call,same story-will be in in 2 weeks.
Fast forward to April of this year and I made my monthly call.Lo and behold they had arrived and were shipping out in 2 days.So they finally arrived 6or7 months later.
To be totally fair I have to admit 2 things--1.each time I talked to them they offered to refund my money,and 2.I originally payed for used like new DPM set.What I got wasn't like new,it was new.
So I guess my patience was finally rewarded.
