My site is using oscommerce. I would like to add these functions to it:
1) Discounts Function - I need to have several types of discounts
a) Percentage of Total Sales
b) Periodical discount, such as month, week or day. For example, may be I will give discount for all items purchased for June
c) By Category discount
d) By item discount , let say only item ABC-101 will be on discount
e) Buy 1, Get 1 Free discount
f) Volume Discount - if buy more than 10K pcs, you get XX% discount
2) Promotion or Salesman code - when people buys from my site, if they have promotion code or salesman name, they can enter during Checkout. Then they would get a discount of whatever percentage that I set. The salesman also get a commission if their names are entered. For salesman code, i need to be able to have more than 1 sales person name entered.
