This is a really stupid question. I've never used the DCPI thing so bear with me:
Do you just go to the customer service counter, ask them for the item w/ that number and when they (hopefully) bring it out you just pick through the box for what you want? Is Target the only place this works? Would it work @ TRU with the SKN #?
That really isn't a stupid question at all, you just haven't ever used the trick before.
What I normally do is first enter the DCPI into one of those price scanners to see if they even have it in back. If they don't I figure it isn't worth my time asking. If they do I'll usually ask one of the stockers if they can check it for me. No one has ever said no to that. Most everytime they are nice and will go get it for me. A few times you will get the certain guys that won't because it breaks the "Collecters Item" poloicy they have in place. When that happens I'll usually ask someone in Housewares or the next department over, and they will normally go check.
You can also try it at the Customer Service counter, they are usually the best about it I've found.
