If you see that product pages in AIMsiStorefront are displaying the same price for both Regular and Sale price (which can be confusing for your customers), please download the latest version of the AIMsi-ASPDNSF Link DLL, which is on the Tri-Tech member portal here: https://www.technology4retailers.com/t-C2B_aePsptHome.aspx. 

After you push products back up to AIMsi, the issue should be resolved.
