None of these faults applies to the Dell Latitude D630 I received from this seller

First of all, the price was exceptionally low for the quality of the machine, the size of the hard drive, and the amount of RAM it came with. The laptop arrived quickly, securely packaged, and I received my first pleasant surprise when I extricated it from the layers of bubble wrap: the computer looked brand new. Once I opened it, this impression was confirmed: there were none of the typical signs of wear on any of the most vulnerable places (palm rests, space bar, et al.) to indicate that this computer had been "rode hard and put away wet." The second pleasant surprise came when I fired up the computer: it booted quickly, came up with a clean, uncluttered screen, and functioned perfectly from the start. When I checked the battery's charge, it showed a full charge of over 3 hours, of which I was admittedly skeptical; as it turned out, I had no reason to be. 

As I began to load the software I would be using most frequently, I found that the battery included did indeed have a long useful working life. The Latitude came with its original-equipment charger, which fully recharges the battery in less than two hours. I have now logged well over two months' constant work on this machine, and I have yet to experience any reason for complaint. I am tempted to buy another one just like it and store it away until I need it; however, by that time, Dell will probably be producing Latitudes that run on anti-matter cells, so I guess I'll wait. Meanwhile, I couldn't be happier with the D630. 

Oh, what do I dislike about the product? There's nothing negative I could say about the Latitude D630 that I couldn't also say about any other laptop by any other manufacturer: it doesn't have a 50-inch screen; the keyboard is in a weird place, requiring the user to type at a weird angle; it doesn't come pre-installed with the American Film Institute's Top 100 movies; and so far, it hasn't guaranteed the sale of any of my screenplays. Other than that, it's everything a laptop computer should be.

No you cannot open a upi on day 2

First: Could someone please clarify how the unpaid item process works? If I open a case manually, can the buyer still leave feedback even if he/she doesn't pay?

Second: I have a note on every single one of my listings that payment is due two days after the auction is over. I have several bidders who must spend hours bidding on my auctions during the weekend, then request an invoice but don't pay for many days! Some have even contacted me in the meantime, but cannot manage to pay! I would like to open unpaid item cases at that two day point, what do you think? I know that some sellers let buyers accumulate items to ship all together (for several weeks in some cases) but I am not one of those sellers. I have a tiny house and do not have the space to organize someone's orders for weeks on end. It is ironic that these tend to be the worst bidders, the ones who want something for absolutely nothing.
