D.,
my husband and i were married by the jop may of last year and then we had our wedding ceremony that september with our family and friends present. We recieved gifts for each service, but no one gave us anything for both, nor did we expect it. I did not think any of our gifts or gift givers were cheap. So, please, don't think yourself cheap.
The only concern our friends and family had was "are you going to celebrate 2 anniversaries every year?" and, of course, the answer is yes, but we told them to pick one they preferred, most of them have chosen september, because that was the formal ceremony. You get to decide when you give a gift. Also note that proper edicate dictates that you have 1 year to give them a wedding gift.
The bottom line is one gift is all that is expected. If they expect more they are just greedy.
