v1.0.3 (2018-9-18)
Ebay made some changes to their layout. Price range items have one parent less and are listed with the class 'prRange' instead of '_DEFAULT'. This is fixed.
Added automatic sorting to "Price + Shipping: lowest first", 200 results per page and filter to "Buy It Now"
Added support for all international sites: at, be, ca, cn, fr, de, in, ie, it, com.au, com.hk, com.my, com.sg, com.tw, co.th, co.uk, nl, ph, pl, es, ch, vn. Thanks to user "hiro neu" for pointing this out!
v1.0.1 (2018-07-31)
I was angry about ebay's lack of action on fake listings.
This script will remove all listings that have multiple prices, eg. looking like "EUR 0.99 to EUR 293.23". They usually have some totally unrelated product for EUR 0.99 and the real product will cost EUR 293.23. If you search with "Price + Shipping: lowest first" it will still show those expensive multi-product listings on the first page.
Now there are three options:
1) Use this script
2) Filter the search with "Sold items"
3) For every page, open developer console and run $('.DEFAULT').parent().parent().parent().parent().parent().parent().remove();
If you decide to use this script, you should define sorting and "items per page" before enabling, because the pagination plugin will crash when any greasemonkey script is run.
This is just an implementation of an stackoverflow question:
