I'm getting ready to request datafeeds from CJ and will have to pay the fee. I'm very new to datafeeds. I have purchased a copy of WebMerge and have used it only to convert a tab delimited excel text file.

I need advice in making my CJ datafeed request. I will ask for datafeeds from clothing companies. I've noticed that some people said they made special requests. Should I ask for a specific format, or do they just come one way? Will everything come in one datafeed, or will they be separate? If I have to request changes, will there be additional fees?

Any info for a newbie will be greatly appreciated
