As one of its daily deals, Best Buy offers the Samsung t199 3G Dual-Band No-Contract Prepaid Smartphone for T-Mobile in Black for $9.99. Opt for in-store pickup to dodge the $2.99 shipping fee. That's tied with our mention form two weeks ago and the lowest price we could find by $9. Features include a 2" color LCD, text messaging, 250-entry phone book, SIM card, five hours of talk time, and six days of standby time. Deal ends today.
