Very impressed w/ orderly arrangement of products for sale, e.g., music, books, movie, etc. Makes sense! Also, the choice of sellers is easy to understand & navigate--I contacted one book seller Solr by email to find out if the used book they were selling was highly dusty (allergies) & they emailed back w/ details & evident concern. Alibris is now my "go-to" source for great prices, selection & quality of sale. Thanks for doing a great job!
