Here's a reply from my second best merchant
In our feed we currently only send masterparts. i.e. not the child parts which include the size. To send both would increase dramatically the size of our feed. i.e. we think maybe 4/5 times the size. We are looking at possibly pushing this through however do have to consider all other affiliates when making a change. Would really help if we could get an understanding of how other people are sending you this data. Would it be possible to send me a copy of the feed you get from someone who has it working.
I dont get how surfdomes sizing attributes are fed into the description. I know you put them there, but when i download their feed from webgains theres no sizing field?
What would shore and others need to do to make datafeedr to utilize sizing?
