In my opinion, I would not ever go this route unless you are holding the stock and have more than 100 items.
I still wouldn't go this route however.
Why?
Because its $49 out of your pocket, to eBay or uBid to try to do your business for you.
And only you know how to do your business. The individuality is key, its what matters!
What if you could get the same, just by going a different route?
How about not using anything at all except the base listing fee, ie: value pack?
You can do such a thing. Listings cost on average $1.70-$5.00 this way on high items.
Then you're not using their extra 'shuffle' to try to make a 'profit'
You can make the profit immediately instead. Put your items onto your 'OWN' store, hosted on a website somewhere for free. There's plenty of places to host for free.
List them all at once, then in any auction/page include a link back to your store.
You'll be shocked and amazed......as you drive traffic like a freight train to your store, people from all over will buy. And only you were able to do this not them. Your individuality caused your store, wherever that is, to become an instant overnight & weekly success.
What if you could, triple & then QUADRUPLE the traffic you send to your store?
And then what if you could list 'ALL' the products at once, even if it was only 20?
The possibilities are endless. And you pay nothing. No monthly fee VS
$49 and the eBay/uBid folks trying to take over and tell you what to do or control everything. No thanks, if you get a break run with it. Freedom is one of the biggest things we take for granted.....Hold onto it
