Did you get a Pre or Pixi? They’re both great phones, but without a Touchstone, spare battery, or case, you’ll be missing out on the full experience.
The PreCentral.net Accessory Store has your back: now through Dec 31st, you can use the coupon code "PCNY" (no quotes) to get 10% off all accessories in the store.
Coupon cannot be applied to shipping, taxes, or software and ends at midnight Pacific on the 31st.
