Quick Question, I have about 15 HP ProDesk 600 G2 Mini Desktop's i7 processor at 2.8ghz 256 SSD HD 16Gig ram Selling for about 5-600$ on ebay. I am going to let them go for cheap and far below value. Pricing them at 300$ I want to know how can I sell them and get the money fast. I was looking at my personal ebay account. Never used it for anything other then buying and it says ill have to wait 30 days after I sell an item to get the money. How can I sell them and get the money right after I sell and ship?
