U O ME is a method to pay an agreed upon amount for special services/products that you have individually negotiated already for with Vaping Watch Inc. It is sold in $1.00 units. Simply buy the number of units equivalent to the dollar amount that you agreed upon with vaping Watch Inc. We will credit your account with that amount and assign it towards the product/service you have requested from us. Please add a note in the cart at checkout to confirm what the amount was for. That will help both yourself and ourselves guarantee we are talking about the same thing. If you buy these without first speaking to us about it.....well......we appreciate the tip!
