(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
