Buying a gift for your boss can be stressful due the reality that there are few guidelines on the process. You don't want to spend too much money on someone that you work with and don't spend your free time with socially and you also don't want to look like the cheapest employee in the office. The trick to being successfully at this gift giving process is choosing an item that's in the middle of the two aforementioned elements above and finding a gift that's not predictable, like a bottle of wine (Not that wine is a bad). You should use this experience to give something unique and create a GOOD lasting impression with your boss.
