I agree about the annoying pencil values some sellers write on album pages. Often, I want to reuse the pages (if they're in good shape) with the stamps still on them. That means laboriously erasing all the pencil marks. Tiresome at best, damaging to stamps at worst. I wish sellers would keep their pencil marks to their own paper and not write them on album pages. Or use a post-it note that can easily be removed. I've also seen that done.
As for Herrick Stamp Company, I used them for years (maybe 20, in fact) as my new issue dealer. They were invariably good in every way with shipments packed well and sent promptly. I never once had a problem with them. It's a company, not an individual, so "on vacation" and other explanations probably don't apply. My guess is that they simply don't monitor eBay
questions for some reason. Or maybe the person in charge of that just isn't paying attention. They have many people working there. I'd make a phone call instead.
Also, Ken, every time you post something here, it reminds me to look at your eBay
listings. Then I bid on some of them. Then I spend money.
