If the charges are the same amount on the same day, sometimes idine's computer thinks they may be duplicate charges, and you will only initially receive credit for one dine.
You may have to FAX in copies of your other receipt(s) to idine to receive your missing credit(s).
One way to avoid this (thinking it's a duplicate charge) is to vary your tips on the dines.
Example - if the bills are $15 each, add a penny or 2 tip - thus your charges are $15.00 and $15.01 - not the same and not duplicates!
