[Plugin: Text Replace] Use of $49 in text replace

I have the text replacement:

::price1:: => Pricing for one hour: 12x Member $ 49, 6x Member $ 55, Guest $ 70.
An additional half hour is only $ 25

It’s on one line. IF I take away the space between the $ and the numbers, the dollar sign and the numbers do not get replaced… it is left blank. Apparently, $49 and the other prices are being interpreted as some code? How can I insert that (some prefix?) or is this a bug?

Thanks!
Rick
