Big Spender for osCommerce is dollar based discounting. Spend over a certain dollar amount, get a discount on other products / receive other products free. Note that in many cases, Paypal does not interoperate correctly with any osCommerce discounting modifications (including mine) by default; changes are required. Please review My osCommerce Payment Integration Notes and test with a free module prior to ordering a paid module.
