I can't beat that 5,000 for $35 but if you would like to avoid duplicates you don't need and guarantee NM condition, take a look at my tradelist/store https://deckbox.org/sets/176581?o=d&p=17&s=b. Most of my bulk is priced between $0.01 and $0.04.
If you're really looking to avoid picking out singles and just get a big box of bulk, I'd be willing to assemble a box of 1,000 pre-origins cards for $10 plus $13.60 shipping.
