The description of the brand new unopened 2015 Dell 3847 with Windows 7 sounded terrific and exciting. However, the contents in the box remain a mystery. The entire experience was poor.There was no packing slip. The packing slip was removed from the plastic slot that usually holds it on the outside of the box. Inside the box, there were no manuals, warranty, registration packet, guide books, or directions . There were no markings or identifiers on the computer or box. it did have a windows 8. disk in the box but no windows 7. Even though I could up grade to Windows 10, I wanted Window 7 as the base program.The box did have a keyboard and mouse.The computer did not boot. I could not tell what options were on the device.I went on line to re-check the options and noticed the price dropped approximately $60. to $806. Since there was no invoice in the box, I would not have known of the price cut.The box arrived at 2 pm and by 6 pm , it was re-packed and ready to be returned.I never have experienced issues like these from Amazon in the past. I don't know if the problems lie with Dell or AmazonThe agent had gone ahead to send me a replacement for the same exact model.  A significant amount of hours has gone into trying to getting this work....but this is the third one being returned for the same reasons. I'll check out the Labor Day sale at Best Buy to check out the models. I must say the telephone staff at Amazon have all been very  helpful , one agent offered me an additional 20% off for the hassle of needing to return the item  twice. Maybe I'll be lucky on three.
