Reservations / Product Code
Do call ahead or email to ensure they have enough quantity. Cite the product code. For example:
Of course you can try to buy from elsewhere. The products above are for the button caps made by EAO AG.10 x EO 51-901.6 blue
5 x EO 41-903.2 red
etc
Be prepared for using alternatives. The 41-903.2 is transparent and the red buttons can look slightly orangeish. But you can add white glue behind the backing to reduce this effect (just be extra careful not to let any glue get between the white backing and the red cap. The 51-901.6 is translucent, not transparent. Removing the protruding pegs from the white backing can be harder.
The staff at Federal know about us and are very friendly.
Colour-matching and Prices
There is actually a variety of alternative products and they all look slightly similar, so please visually check every button to make sure the colours match etc.
Try to get the type with two-prong plastic backing (41-903) as that backing may be easier to remove:

The variety of sources also means the prices may not be the same. Generally each cap sells for $3.50 plus 7% GST. If they run out, they might substitute with something almost identical but with some price difference.
