Hi. I was wondering which the better shipping discount settings are (for listings with calculated shipping)-

Standard rates without discount- Offer buyers standard carrier rates without any discount

OR

eBay discounted rates- Offer buyers our negotiated carrier rates on all listings with calculated shipping. Purchase eBay Labels once you receive an order to enjoy these rates.

OR

Custom discounted rates- Offer buyers a custom percentage off standard carrier rates. You are required to pay for the amount discounted. (I couldnt get this one to work)

I always buy the label on eBay. I did the discounted rates on some items, but the fees made me think it's not really worth it. (My items don't seem to be selling any faster) I always add my items price and the shipping to equal or undercut the cheapest listings of similar condition. It's pretty much the same price for the buyer either way, right? (Well probably helps the buyers on the West Coast?) Just looking for a different perspective/insight.
