(probably not news for veterans here)
Good tip! There aren't many components worth over-ordering, but I spent 30 minutes going through the BOM and shaved about $5.50 off the price. Thought I might save others the trouble..
1n4148 Diodes (BOM = 95 x $0.053 each ($5.04); but 100 are x $0.019 ($1.90))
1Kohm 1/4W 1% Resistors (BOM = 58 x $0.08 ($4.64); but 100 are x $0.032 ($3.20))
22Kohm 1/4W 1% Resistors (BOM = 45 x $0.092 ($4.14); but 100 are x $0.037 ($3.70))
100Kohm 1/4W 5% Resistors (BOM = 91 x $0.021 ($1.91); but 100 are x $0.013 ($1.30))
Also, though it appears to be only 2 days old, there are already 3 items backordered on the BOM:
138x 10K ohm 1/4W 1% Resistors (currently stocked replacement:
https://www.mouser.com/Search/ProductDe ... 5FBF52-10K) [note that 200 units cost less than 138)
8x Film Capacitors 100volts 1000pF 5% (currently stocked, cheaper replacement:
http://www.mouser.com/ProductDetail/Kem ... vLAx2PU%3d) [note that 10 units cost the same as 8)
4x LED Mounting Hardware (currently stocked, cheaper replacement:
http://www.mouser.com/ProductDetail/Biv ... c15%2fg%3d) [same as in BOM, but white instead of black at 1/2 the price)
New BOM total: $174.49
Old/Current BOM total: $182.26
