Okay i am going to explain this as best as possible.
Currently i have a excel file with an inventory of 200-300 items with prices and availability of them. The prices and availability are constantly updated with a website to check to see if the price changes or it goes out of stock.
Now i am also listing these items on amazon. say the excel file updates a specific item with OUT OF STOCK status. the excel file has to be able to communicate with my amazon seller account to end the listing of the item.
And vise versa.. so when it comes back to IN STOCK it has to re-list the item.'
You will probably need more explanation but thats the best i can do over here. You can talk on skype / aim.. what ever and i will show examples on teamvieer.
