Wow, that pricing is out of CRTL.
Yes, that's what I thought.
Look what blank colored modifiers Round3 still has for you at 30 cents each:
1 left ..... BLUEBLANKR4U225.........0 $0.3......1 Blue blank key
1 left ..... BLUEBLANKR4U275.........0 $0.3......1 Blue blank key
in stock ... ORANGEBLANKR4U125.......0 $0.3......1 Orange blank key
in stock ... CLEARBLANKR4U125........0 $0.3......1 Clear blank key
in stock ... BLACKBLANKR4U125........0 $0.3......1 Black blank key
in stock ... WHITEBLANKR4U125........0 $0.3......1 White blank key
Not exactly an RGB set, but for $1.80/set, it's hard to complain.
I think Round4 (in a distant future) could offer similar pricing for a RGB set.
