No, AT&T does not have any current coupons that their current customers can use. They usually only offer coupons to new customers.
A friend of mine told me that if you sign up for Verizon wireless and go for the contracted plan you'll get a free cellphone. That will save you at least a few hundred dollars.
Yes, there are current coupons available for the IPhone 4s for Verizon. You can find these coupons at www.retailmenot.com
You will need to read the description of each offer. Some of them will say that they are for new customers only, while others are for everyone.
Businesses offer coupons when they intend to increase sales/encourage new customers to sign up.I assume Netflix coupons do expire after a certain interval of time or after a quota has been reached
It's much more difficult and expensive to obtain new customers than keep old ones. To get new customers, companies have to convince them that it's worth leaving their normal brand (for example, Verizon trying to convince Sprint customers to leave Sprint for Verizon). It's much easier and less expensive for a company to offer their current customers discounts or deals if they consider leaving for another brand (i.e. Sprint offering their customers a free month of service if they don't go to Verizon).
You can check out the deals from Verizon since they always offer deep discounts to attract customers.
You might consider going directly though the Verizon website. They offer discounts to new customers and current customers looking to upgrade, and online prices are often even cheaper than in the stores. Also, you could try searching on Ebay for a new or like new phone at a deeply discounted price.
Yes verizon does carry a smart phone and they offer good discounts on new service plans. You can also find more coupons for verizon at http://www.wow-coupons.com/view-merchant.php?Store_Name=Verizon%20Wireless&Id=612&gclid=CNuLudKBrKsCFacaQgodjXF46Q and they have a coupon for the smart phone and other services on this site.
Verizon does carry iPhone (mainly iPhone 4), though it isn't selling as well as expected. Part of this is due to the discontinuing of unlimited data and changing to a tiered data package for new customers.
Glade does offer coupons online both through the Glade site and on other sites. Many of these coupons are for new products, but it does not look like they release the coupons before the products.
Sprint, T-Mobile, and Verizon all offer excellent plans for new and existing customers. Many plans have unlimited data and deep discounts on new phones.
