So I'm ready to post a few of the items on Loupe Troop. How do I make sure that the person who called 'dibs' gets first chance to buy the item?
Personally what I do is I go and order of first request. The first person to request the item and keep in contact and commit to purchasing and paying is the one I honor. Then I go down the list in order of additional requests. Generally speaking unless you have things listed at a really really low price or unless the item is very rare you will not have multiple buyers.
If I have multiple interested parties I let the people behind them know and I give them a deadline, the first inquiry, to make their decision and pay the invoice. I think 24 hours is reasonable. A lot of times if you tell people that you have other folks interested and you need to know if they would like to move ahead with the purchase, they will let you know pretty quickly.
I usually charge $10 for flat rate shipping in the United States because I like to get a bubble mailer, and I also like to get bubble wrap to individually wrap the items. If you do a priority shipping box with the included $50 insurance and nothing else on top of that that usually runs about $9. That is for a small box. I also offer combined shipping for items and if you have people that buy multiple things that would make sense here.
I also want to make a suggestion to you to make your listings easier. I would do a listing on loupe troop by the type of item and the material.
For example, everything that is a sterling silver ring I would put in one tray and put all of those pieces in one listing with the details for each item with a number just as you have done it. If you have 14 karat gold rings I would do the same thing for those. If you have earrings I would also do those separately and I would separate them out into silver and gold, as well as costume. that way, it is easier for buyers to figure out what exactly you have because you have so much.
