Worked on the price changes and $4/$9 rounding for most of today. It's inter-woven into everything! Because of the nature of our custom system builder the shopping cart doesn't store the contents of the system, so the discount price must be pulled out and calculated on the fly per-section. Probably about 20 files needed changing! But, I've done it and It appears to test OK. I'm going to get a few people to try it out now and check everything with a calculator.
I also went through my phone and found this join that I made on a CAT-5 cable in the ceiling cavity. That was a feat =)
