1.How do You Put or Collect Items on eBay From Argos?
Once the item has been processed for collection by Argos you will receive an email and text message with a collection code.
When you receive the code you can then collect the item from the Argos store.
2.Why eBay wont Let me Revise or Pay for My Item?
If you can't revise the actual listing maybe you can post the member question and your response to it about the yellowing in the auction. I don't think that counts as revising the listing.
it sounds like maybe you have reached the selling limit if your account is already linked.
You can't revise the auction either because (1) your ebay account and your paypal account aren't properly linked (so check that first), or (2) ebay has limits on the number of "high ticket" items that you're allowed to sell at one time! Unfortunately, ebay neglects to TELL you about #2 when you list, so if you list some bare bones info with the intention to go back and add to the description or add more pics, you are SOL in a huge way.
I found this out the hard way after listing 4 LV items. Because I couldn't go back to add more pics, I think this reduced my chances for higher bids. It took 3 emails and 3 "live" chats with ebay customer service reps before someone could tell me what the heck was going on with my listings. Of course, no one could properly answer my question until day 6 of a 7-day auction.
