Now you can yes
Not really. Once you buy the products the shipping company cannot hold them for a long period of time. Three weeks might be too long. Best to make sure in advance. That said, their delivery service is not reliable. I've had a shipment scheduled and cancelled 3 times in a row, with no notification. If you have the opportunity to take your purchases with you, that might save you time and frustration. Also, dont forget to open all the packages once you've bought them to verify nothing is broken and the items are the exact color and model you paid for.
IKEA should have the ability to do that. They just bought TaskRabbit and that was a task based website.
