I'd like to reorder with the same seller, but strangely I can't find the seller even though I scrolled to page 93. Seems I'm being prevented from using that seller.
Click on the messages menu on the left side and click the search icon on top and write down the name of the seller, you'll find him/her.
Just press on orders under your Udimi account
You can also search for a vendor by his name in the Find Sellers section. Click the "Keyword" button and put his name in the search field.
Please contact the customer support team in the Help section if you'll have more questions.
