Probably a couple thousand...
At one point I was receiving 3-4 pairs of shoes a week, and was making multiple trips to Blends OC and just picking stuff up. I think I made three trips in a day once and picked up Union 180s, Nature of Communication AF1s, and some different Vans. Bought 3 pairs of Guccis in one day (Sk8 highs, white mocs, and brown boots kind of like Timbs but more streamlined.
Looking back it was such a stupid way to spend money - I think I ended up +$1200 after selling about 35 pairs, and now I'm left with a bunch of non-heat that is worthless - still have at least 10 DS shoes...mixed Terminators and AM90s - that nobody wants and I will probably never wear.
