Looks like i found a little bug: 
Really digging the aesthetics though, and even the balancing is nice. :)
Nice catch, thanks for reporting this! Fixed in 1.2.1 release. (Technical details: number-to-array convertor that runs on startup added extra leading zero to numbers that had a length divisible by three, and array to array multiplications with specific numbers would preserve the zero, leading to price format the code was not prepared to handle.)
