Hi Amelia,
FILLER
Fillers (or at least a 1/2 inch thick end panel) do give you some leeway for clearance--particularly if walls are wonky.)
If you had a door instead of drawers, I'd recommend filler. Two elements determine how wide you can open a door: (1) The hinge and (2) the amount of free space you have on the hinge side of the cabinet.
ORDERING LONG DISTANCE
1) Confirm that the Tempe store does long-distance orders. Schaumberg is my closest store and they no longer do fax orders. Did your local store say they could take your order but have items come from a second store? Double-check to see if that's even an option for you.
2) Consider going with IKEA Direct. You have to spend time writing up your order anyway so you could compare the costs of having the store delivering it versus IKEA Direct. Additionally, the stores are so swamped you might get better customer service from IKEA Direct!
This thread describes
my positive IKEA Direct experience at the end of May '07.
And here's my
follow-up thread describing the delivery itself.
You'll be working with one IKEAn and there will be a bit of back and forth as you double and triple-check your order. Write up your order carefully in Word with each cabinet listed in a separate table. Include notes about modifications too (such as "no doors" or "extra pair of shelves" or "no hinges.")
In my case, I spent a lot of time writing up the order and IKEAn Marcus Turner and I talked several times on the phone to discuss the order.
Be sure to ask your IKEAn (whether it's your local store or IKEA Direct) about any upcoming specials for delivery. When I ordered from IKEA Direct in May '07, orders over $3K had shipping 50% off.
You're fortunate to live near an IKEA. I have to admit that I'm not so keen on ordering anything in the store. My recent visit to Schaumberg was maddening. It was Thursday morning--around 11 a.m. and already busy in the kitchen department. I think the entire store has about 10 people working there.
It's a tedious process whether you do your order in the store or via IKEA Direct. I found working from home was more tolerable.
Good luck!
