Great job. One suggestion is to make sure you bring plenty of change. Most people stop at a cash machine and have $20 bills. That is great if all your items cost $20 but if all of your items are in what I call even dollars ($5, $10, $20, $25,....) bring at least a $100 in $5's and $50 in $10's. If you have items in $1's ($3, $6, $22,....) bring at least $25 in $1's. I typically bring a $200 to start with.
