We asked for money as a gift, but some people still bought us things. We only asked because we didn't need anything. We didn't mind either way though. We used the money to pay for our honeymoon.
We generally got between $50 & $100. XH's boss gave us $30 & the girls in the office put in $20 each, so that was $60.
The majority were $50. We also gave $50 at a wedding we went too,as well as a small gift.

In your case, don't worry about the money. I honestly didn't remember who gve me what when it came to the money. I don't think any of our bridal party did.
