I will do holds if you can't pay right that minute and you are afraid someone else will buy it before you get to it. You need to email me at firstname.lastname@example.org with the item name(s) and I will hold them for you. I will NOT hold an item for more than 5 days in most situations.
If you are looking at an item and then come back later and it has disappeared, that is because someone has already purchased it. Sorry! If you can't buy it right away, ask me if I can hold it for you.
