I'm surprised your credit card hasn't been flagged for suspicious activity given the amount of gas you must've been buying over the last few days!!
Congrats on the purchase though! As for the tint, a few small bubbles on a fresh tint job are normal as long as they go away after 1-2 days; it's just the adhesive drying. Just make sure not to open and shut your windows for 3-5 days, and it can also be helpful to flatten out any rough spots by slowly and firmly pressing the edge of a credit card along your window every 24 hours for the first 3 days. I did that over the dot matrix area while the tint was curing, and while it still doesn't look perfect in that area (I don't think it ever could without altering the dots themselves), that area looks better on my car than most other tints I've seen.
But yeah, if the bubbles are still there after 2-3 days or so, they need to do it again.
