purveyor на английском языке:

I work as a musical records seller.

This book, which was once a best seller, is now out of print.

After considerable argument, the buyer and the seller finally came to terms.

He began to suspect something was wrong when the seller didn't allow him to test the item before buying it.

I built up some debts at the rice seller and at the greengrocer.

In case of any problems with data transfer, please contact your local Internet service provider.

I changed the internet provider recently.

Netflix is an American provider of on-demand internet streaming media.

My husband isn't quite the provider he should be.
