Target offers the Vtech DECT 6.0 Cordless Phone System, model no. CS6519, for $12.99. Choose in-store pickup to avoid the $8.99 shipping charge. That's the lowest total price we could find by $12. It features an answering system, speakerphone, 50 name-and-number phonebook directory, call screening, and expandability up to five handsets.

Update: It's now available for in-store pickup only.
