See post 27 for the actual Costco price tag for the item.
I went yesterday to purchase the Dell, but they only had the display available and all the HP's were gone. Saw a display Lenovo 430 IdeaCentre for $300. Purchased that instead of the Dell and took it home. Very disappointed with it. Returned it this morning and glad that the display Dell was still available. Purchased it and now using it.
Just for the record, check post #6. You are welcome.
Last time I bought a display from Costco, they gave me 20% off. Hope you got a discount too, but consider yourself lucky that at least the display was available. BTW, if you don't like it for some reason, consider selling it on eBay.
