was wondering if i could set it so that when im using the posting feater at the AH it scans for any auctions for that item alone, and sets the price for it.

currently the only way know how to keep my prices up to date is to scan the entire AH.

If you're using the simple version of the AH posting interface (and possibly even the 'full' version), there should be a little button near the bottom right corner of the AH screen that says refresh. When you select that, it refreshes just information about the item you have in the posting section. Hope this helps. Let me know if you have trouble finding it, and I'll attempt to take a screen shot and upload it somewhere so you can see. :)
