In the event that a member/sponsor does not have what you're looking for :

You can buy 50 slip sinkers (2oz egg shaped weights) on eBay for < $25 : https://www.ebay.com/p/50pcs-2oz-Egg...ead/1339220988

I would also have suggested Crawdad's Fishing Tackle website, for "inline trolling sinkers" .... but, they are not "slip" style sinkers, but are the torpedo shaped weights with the metal loops at each end (and/or with swivels). 50 of the 2oz ones at Crawdad's would run you around $45 plus shipping (but has free shipping on orders of $50 or more).
