Anxiety

Ahh...it's driving me crazy...I doubt I would be able to sleep tonight...
How I wish I didn't order Harry Potter and the Deathly Hallows from Popular bookstore...I made the wrong choice. I should have just wait a little longer. I pre-ordered the book during March, and I got a letter from the post office on April. The offer made by the post office is way better...I still remembered the Half-Blood Prince, I got the book at about 8am.
I 'm worried about my loss of receipt, I'm afraid the staff will give me trouble? I know I am paranoid, but I can't help feeling that way. However, I think everything will be fine, c'mon, I've already paid a deposit. If they are going to create trouble for me, they will get it from me.
One more thing, their service is bad. I e-mailed Popular at Northpoint last week, and guess what, I did not get a reply from them. What kind of service is that? Compare to the National Library Board, they are way below them. I e-mailed to the NLB and got a reply from them the next day. This is what I call good service...
What can I do? I made the wrong decision, so I must make it right...
Countdown to Harry Potter and the Deathly Hallows:
less than 24 hours!
