Just to let you know, I am aware people are able to know I have important stuff in my bag. Right now I am around a bunch of other people on laptops also. They even said they don't like my laptop, they like Windows and Bill Gates. They're from France.
Today, I found a cheaper place for groceries and stuff. I was happy about that. I also bought batteries for my camera.
Budget:
Groceries: €10 ($15.62)
Hostel: €18.5 (28.89)
Deposit on Hostel in Edinburgh: £3 ($6.20) + $2.00 service charge
Total: $52.51
