Checking High to Low

I read alot about checking accounts putting higher amounts through before lower amounts, but I've never really been able to keep track if that's really true since I used debit for everything. Since I've successfully completed almost my entire first month on the "cash diet," I have only used my debit card for bills and our mini overnight vacation. My gas literally took almost an entire week to clear the bank to let other charges I made after it go through.

It went in the following order:
ED transfer- $100
Hotel room- $83
Groceries- $39
Gas- $26 ($1 over budget too!)

When it should have been hotel, gas, ED, then groceries. Of course, it's a good thing it pulled the savings money first, but I was getting pissed off that whole week my gas I charged wasn't showing up because if I didn't fill up on the exact same day every two weeks, I probably would have forgotten about it. It sure looks like the high to low is true after this though!
