I'll try to list screen shots because I know this is hard to see quickly. If an item is bought out without any bids, there are certain discounts. Otherwise, bid away.
Buy 1 at buyout=5% discount
Buy 2 at buyout=10% discount
Buy 3 or more at buyout=15% discount
1) Sold
2) through 4) have no buyout prices yet
5) b/o=35k
6) b/o=35k
7) Sold
8) b/o=45k
9) b/o=40k
10) b/o=100k
11) b/o=70k
12) b/o=50k
13) b/o=50k
can also use a 15>50 brute sword as a payment method (valued at 200k) or an insightful staff head+5 (valued at 20k)
