Netbook Shipment Question?

So I ordered a netbook on Friday, the company said they would have it at my doorstep the next business day(they are in close proximity). It is now Monday, I was just wondering, when do you guys think it will come? I'm just kind of nervous because I don't trust shipping expensive items, but I needed a netbook fairly quickly and the one I had my eyes on was out of stock all over my neighborhood. Generally I don't trust shipping at all(bad experiences); the product hardly ever arrives on time and if it does it is usually not exactly what you had ordered. I need this by late Tuesday/early Wednesday, do you guys think it will arrive by then? Just a little poll. :D
