Ordered an item and put the apartment number in for shipping. They sent me an email to confirm that everything was correct, apartment number was included. They shipped the item and UPS sends me an email stating my package was set to arrive tomorrow... but there was no apartment number listed for shipment. So now the package is just going to the building as a whole. I sent them an email asking them to correct it. No response, so I called UPS myself. They advised that indeed no apartment number was given, so I corrected it with them. CDW then sent me an email back stating "ship address has apt #". Yeah... you guys suck. User's recommendation: Go somewhere else.
