@Jack_mcs What version of Easy Populate will still work with osCommerce Online Merchant v2.3.4.1 CE (Frozen)
On an older version, we have set the "Price includes tax" to true, but the issue we are having is even though we have set our price decimal places to 2 we are getting prices with 3 digits for cents and then on the retail side we are often getting a price like $12.96 instead of $12.95
