After a while they don't ask questions anymore. I just tell them I am a collector.
I didn't start with any friends at the bank.. but I have made a few, since I take all their CWR and they never have to ship.
For up to 8 boxes I just carry it out in 2 canvas tote bags.. 4 per side. For 24 boxes, I use a dolly.. 660 pound capacity. The dolly is one of the best investments you can make if you are going to step up your volume.
The reason you are getting funny looks is you are only asking for 1 or 2 boxes.. I use that many boxes just to buy gas. Of course it does sometimes take time to get set up for reasonable size orders.. you want to get to know the folks at the bank. Of course you could step up your volume if you did 2 boxes each at several banks.. but that is a lot of driving around.
If your percentages are low.. just sort more. If your percentages are high.. just sort more
