$1040/50 = $20.80+ set cost isn't so bad, probably come to $90 a set
a tenkeyless set you would only need 87 legends and per set is
25 sets $73.01 / set
50 sets $52.42 / set
75 sets $45.56 / set
100 sets $42.13 / set
with the legend fee you're looking at $70 a set at 50 sets not including shipping from SP to distributor and then to you, probably $10 more
I did my homework for a group buy wanted to do, but dunno if I can attract 50 people as I don't think people would like the 25 set pricing
