Jesus wept, that's hard!

or 'retail store'?

http://en.wikipedia.org/wiki/Anchor_store

Definition: A major retail store used to drive business to smaller retailers. These larger department stores or grocery stores are generally part of a retail chain and are the prominent business in a shopping mall.
Examples:
Without its anchor store, customers would no longer have a reason to shop at our local mall.

- I think your comments above actually make "walk-in stores" the right contrast and to the traditional business styles of door-to-door sales and mail-order sales.

- You also mention that they are stores where "basically they've opened up stores where people can come in to buy their products and services." So, they are stores where people can "walk in" to buy their products and services.

Walk-in stores, by definition, are those physical, brick-and-mortar retail stores that customers go into to buy goods. You have to actually go into the store to purchase. There's no salesman who comes to your home/office to sell you his goods, nor do the goods come to your home/office via mail order.

Here's a Consumer Reports website using the term:

Weigh Web and walk-in stores
According to our Annual Electronics Buying Survey, electronics items are now as likely to be bought online as in walk-in stores. Websites dominated the high-scoring retailers in our Ratings of places to buy major electronics and computers (both are available to subscribers). Many of the online retailers were standouts for both price and selection.
But the main advantage of many of the higher-rated walk-in stores—fine customer service—may be more important than ever this holiday season.

Here’s another website using "walk-in stores" (This one's on Dr. Jay’s)
