Free item with purchase of $X or more

I am currently using the Dangling Carrot Module:
http://www.zen-cart.com/forum/showthread.php?t=34275&highlight=add+free+product

However it only allows for one product to be free. I have 2 specials one is
for $25 or more receive item A
for $50 or more receive item A and item B

Is there another module that allows this or how can I modify this module to fit one more free item.

If you are looking for the dangling carrot or "Free item with purchase of $X or more" module. It is explained here http://www.zen-cart.com/forum/showthread.php?t=34275&highlight=Dangling+Carrot+Module&page=2

The original OS Commerce dangling carrot module allows you to set as many gifts as you like, and give a different threshold for each.

I've done the port to Zen Cart and just need to package it up and write the install read me.

Look out for it in downloads soon.
