As this ("deal on ebay") has been a recurring theme for some time (these sorts of offers happen on other items, nanovna is one of the subject items for this sort of spam/scam), I would like to suggest the following:
The majority of these non-delivery "deals" arise from misuse of an existing ebay account. If you purchase from one of these listings, you can (and very much should) seek a refund from ebay after the delivery time passes with no delivery.
Almost all of these listings share common characteristics - abnormal buy-it-now pricing (<USD 25), few seller feedbacks (<100, sometimes very few with private or hidden details), no other related items listed (i.e., other items that don't seem to be rf electronics), and no evidence of feedback for sale/delivery of the nanovna. Be sure you're looking at a listing for the nanovna proper (there are numerous multi-item listings that show a price range and might initially look faulty but are not necessarily so.)
Any ebay user can click "report item" link (navigation for US version users is this, other languages may vary --- right side, part way down the screen to the right of "shipping and payments", you may need to scroll down to find it, as it's a simple text link and not very easy to see). Click on "report item" (then you may need to re-supply your ebay password), then choose report category = "listing practices", then choose from reason for report = "fraudulent listing activities", then choose from detailed description = "you suspect that a listing is fraudulent". Finally, click submit report. ebay usually will remove these listings sooner than might otherwise be the case. Doing this properly may help reduce the preponderance of these dead-end listings.
Thank you for your interest in and support of nanovna-users,
Dave
