Groupon has offered daily coupons and discount tips based on
where site visitors are in both mobile and PC version sites. Google has offered
suggested information or advertisement automatic engines based on Gmail inbox
mail subjects and contents. Social networking and free email companies can
establish effective advertisement software to offer right products and services
to online users or subscribers. Brick-and-mortar stores usually send coupon
booklets and mails to local shoppers, card account holders and sign-up
newsletter subscribers. Groupon can survive as long as online subscribers and
visitors like the ways Groupon is doing compared to other methods of receiving
daily best deals on merchandises and services. Groupon has just taken a dual
role of in-store coupons and postal coupon mails exposing or displaying in
front of prospective shoppers. Each person may look for some special deals on
specific products and services during a year.
