Yes, new units usually come with a 1-year limited warranty from Texas Instruments. Be careful when buying "used" as this may not apply.
Why is the sales tax calculated on the discounted price?
In most jurisdictions, sales tax is applied to the actual transaction price (the price after coupons), not the MSRP.

Buying in-store saves shipping costs but may have higher base prices. Online offers more variety and coupon opportunities. Use this calculator to compare the "Out-the-Door" price of both options.

Does the color of the calculator affect the price?
Sometimes. Limited edition colors or "Performance" series colors can cost $10-$20 more than standard colors.
How do I know if a deal is real?
If a price seems too good to be true (e.g., $50 for a new unit), check for shipping fees. Sellers often inflate shipping costs to make the list price look low. This calculator reveals the true total cost.
