Hi, My name's PJ.
Yes, I mainly sell on eBay, but I've started selling software on Amazon. Been selling software & computer hardware for the last 15 or so years, at computer shows (dying venue with the advent of the internet), a B&M store for 6 years & on-line for 3 years. Selling software is like selling anything else...you have to research the market, find suppliers, etc.
"keep the minimum value of the books you sell as high as you can in relation to your knowledge then keep trying to raise it. If you start at a base of $10.00 then simply never list a book below that price (and never acquire that kind of stock- even if it's free"
I've started selling books to clear out my personal collection. Retiring in the next couple years & we're selling everything & buying a boat to 'sail the 7 seas'. So I have a wide range of product...not only paperback novels, but a few older hardbacks, which research shows are quite uncommon, with selling prices over $100.00, old (75-100) year old misc, hardcover books in the 10-20 year old range, collection of VHS tapes.
So for starters, I really CAN'T have a 'start base'. I've sold some for $0.29, others for $18.00. If I decide to pursue this & go out and acquire books to sell, you say to pick a price as a base level. What do you do when you buy a 'lot' of books...some more valuable than others? What do you do with the pieces that are less costly than your minimum 'base price'?
In my experience of selling, I offer a whole range of prices. That way I have something for everyone...broadens my customer base. Since I'm not intending on becoming a major player in bookselling, I'm not concerned with warehouse space for storage, and anyway, I DO have a warehouse that we've used for years for our software business. So having space for low end books isn't an issue.
I might ask, however, (not asking for trade secrets), where can I go to research info on the value of books? Amazon prices are so crazy...from a penny to MANY dollars for the same book. I know, price is based on supply & demand, but was just wondering where others go to look for info on books. (I hope this isn't asking for info that others would feel is only acquired after years of hard work...I don't want to start off our relationship here getting flamed, as so often the case on discussion boards elsewhere!! If this is an inappropriate question, I quickly retract it...move on to something else!
