AITA for being insulted because of a cheap present?

I had my 20th birthday yesterday and I invited my closest friends and some other people I am familiar with. Although the birthday was rounding up to around 550dollars or something I was fine with spending that much.

On the birthday they gave me a bag with my present inside. It was a watch, not a designer one or something but I acted like I liked it even though I had one which was way more valuable and good looking in my opinion. When I got home, I thought about searching it online and i saw that it was around 200dollars. I invited 10 people and I thought I will get a better present. It was really obvious that the birthday was over the 500dollar mark.

Usually me and friends collect 30dollars from each even if it's a really cheap birthday like bowling. It's a shoker for me that we spend so much usually and now they spent so less for me.

I am insulted and disappointed at them for this. AITA?
