Yes, many thanks Tonka for following through on this.
I'll may later regret saying this, but ....
If folks want to DM their lists to me, I can collate them, remove dupes, and then pass them along to Tonka. Should only take you a few mins.
go to manage inventory page
set page max list to 250 items (not sure how I did this)
search for "discontinued"
Highlight all the search results. copy (Ctrl-C) and paste them into WordPad (or some other plain-text equivalent) doc. (important **not** Word. WordPad will save as plain text... no meta data)
save and send
If you want to delete some info, like quantity listed, that's OK by me. All I need is the "B0..." ASIN field.
