2017 usps priority flat padded, does ebay charge retail or commercial?

[redrockwhale]

Hi, im a small seller and I listed a jean. I just noticed that priority flat rate padded pricing is different. Retail is $7.20 commercial is $6.50 , I must type out the flat rate shipping cost for buyers. Should I type in retail rate or commercial rate. I do print through ebay and postage cost will be deducted thru my paypal account. Does ebay charge retail or commercial for usps First class package?  Very confused : -( help me please

eBay charges the online rate for all labels except Media Mail.  So the ebay postage cost for a Priority padded FRE would be $6.50.
