Each code on the guide legend will show where that product feed from that specific company will go: IE: "PS" will go to 7 websites! out of that 4 are single data feeds, 3 more are 2 data feeds and 1 will eventually have 3 product data feeds. Site 1 (domain name) : PS (company data feed) Site 2: PS Site 3: PS Site 4: PS & AL Data Feeds Site 5: PS, AL & T Data feeds Etc etc. refer to guide that i will send upon request. now only a couple of the sites will say 3 data feeds, yet i only have 2 data feeds at the current time due to the fact the third company is building the data feeds as we speak and that will be a later project. so in total there are currently 6 different data feeds from 6 different companies The main Data Feed is company PS and that datafeed is a updated daily one with inventory levels. The secondary data feed is another one that updates daily or weekly. the third updates weekly i think. And the remainder are just a bulk datafeed upload. With all of them (especially the updated daily ones) i would like to have the script written to add in our set price (so lets say wholesale is $5 i want to double it, i would like it to show up on the site as $10 etc. Please let me know if you need more etc.
