I have 1,000 SKUs. Each SKU comes in 4 different sizes. I’m trying to figure out the best way to list them:

4,000 separate listings — one listing per size. Would this violate eBay’s duplicate listing policy? The products are almost identical except for size.

1,000 variant listings — each listing with 4 size options. This would save on listing fees and be easier to manage.

Which approach would you recommend? I’m concerned about duplicate listing penalties if I go with option 1.

Also, I’m having trouble with eBay’s bulk upload template. I keep getting errors on the “item location” field. I’ve tried multiple formats but can’t figure out what eBay wants. How should I fill that field for a warehouse in Germany?
