session state, shopping basket, arrays

hi dudes, just writing a dotnetnuke module, basicly a shopping basket control, i when a user clicks to add a product to the besket, i want to add it to the session state, then get the basket on postback? not sure to pull the infomation from session state, then run it againt my sql server and populate my datalist acordingly

not sure if this is the best way to do this, since im new to this all, any ideas please let me know, got 2 weeks to finish this lol, if session state is not the best way to be doing this please let me know, cheers
