Having a business myself, yes internet can increase the number of sales made, but because companies are not pushing the authorized selling clauses, the mark-ups are so low, that service as a seller to consumer is at an all time low for most places.

When in the past a company would buy an item for $100, and sell it for $150. There was room for bargains for multiple purchases and extra's.

Now we purchase this item for $100 and to sell it with all the competition we sell it for $110 or $115, why bother!!!

Unles I can sell 30 times more than I did, so there goes your one on one type sale
