The Purchase-Triggered Giveaway Entry Writer

Act as a bonus creator. Help me write the copy for an offer where every purchase during a period automatically enters the customer into a high-value giveaway.

• Giveaway Prize: [e.g., "A year's supply of product / A $1000 shopping spree"]

Task: Write the promotional copy. This is a "tag-on" offer that increases the perceived value of any purchase. Clearly state that every single order is an automatic entry. This helps overcome purchase hesitation by adding an exciting, potential secondary benefit.
