Inserting Multiple Records of Info In one Word Mail Merge Document

I have an Access database with a thousand rows. I want to write a mail merge letter to customers with a listing of items they bought from us. I'm getting the customer mailing info from this table as well.

My question is, how do I get word to have a table of what they bought? I'm getting 1,000 mail merge letters and I really only want 750.... which is the number of individual customers I have. Some of these customers have placed multiple orders.

I have thought about doing this all in Access and having a sub-report. That would be easy and I can do that but I loose all of the word processing ease of Word and I don't think the report from Access would really look as good as if it came out of Word (kearning, leading and other nuances that Word has that access doesn't).

Any thoughts? I have read some tutorials on how to do this but haven't had any luck getting it to work. They are the tutorials that suggest the mergeseq field and loop through it.  If anybody has a working example of this, I'd love to see it.
