Master Products - MS2 in General Add-Ons Support Posted March 31, 2007 This contribution looks to be (maybe) what I need. I've read much of this HUGE thread, but I'm still unsure if it can do the following, so I thought I'd ask... :) We sell small router boards that have various cards & options. Right now, we have pull down menus using the Attributes, which from the customer side is pretty much OK. However, from our side, shipping weights aren't updated with attributes (although there is a contribution for that I see) and attributes don't update quantities of the 'optional items', some of which we also sell as individual items, and some we don't. We want to have accurate real time stock quantities, and I think this Master/Slave contribution might be the ticket. Right now we have people order a bundle, but might not know that one of the 'options' is sold out. Also, we have the Qty Price Break contribution module installed, which is fine right now, EXCEPT that I'd like to allow customers to purchase in quantity blocks like: 1, 2, 3, 4, 5, 10, 15, 25. Right now, if I set it at blocks of 5, then a customer that wants just 2 boards is out of luck. If I set it to 1 each, customers can order 13 or 19, which is a pain for me. And finally, some customers want to buy bare boards, while some want 2 or 3 or 5 options. I don't want to allow a customer to buy 1 board and then 50 power supplies at the special bundled price. However, if they want to order 25 boards but only 10 power supplies, that would be fine - so basically a limit that each of the slave options would be limited to the same or less than the master or primary item. Thank you for your help / suggestions.
