Important Notes:
1. Starting with extension version 1.2.15 we have adopted a license key for all our extensions. Your extension will only work if you have a validated license key entered for the location where your extension is installed. Refer to here for more details on how license keys work.
2. In our opinion AbanteCart v 1.2.14 is extremely problematic and requires a large number of patch files to work correctly. Our recommendation is to upgrade v 1.2.14 to AbanteCart v 1.2.15.
This extension v 1.2.15 is tested to work with AbanteCart v 1.2.15. It may work with AbanteCart v 1.2.14 if all the patch files have been updated but we don't recommend you using AbanteCart v 1.2.14.

AbanteCart Version(s) 1.2.15 use Multiple Price Changer v 1.2.15.
AbanteCart Version(s) 1.2.6-1.2.13 use Multiple Price Changer v 1.2.6.

This extensions helps you to change multiple product base price at the same time. You can filter products by categories, manufacturers or both of them at the same time. The extension also will automatically create a backup sql file so you can anytime restore the previous or original base price.
