We offer member discounts on specific items, but not via percentage -- rather, individual pricing on specific items. I would like to use this Group Pricing (per item) plugin:

However, the plugin is dated 2015 and upon reading further, ran acros this thread cautioning use (in version 1.5.4) until plugin is updated:

My question: Is there another way to accomplish my goals? Otherwise, does this plugin work well with version 1.5.5? It appears to be the only group pricing with the per item option shown in the list of plugins.

Thx.
