Let us take some of the stress out of holiday gift buying this season by giving you more time to qualify for price adjustments. Price adjustments on purchases are available 10/8/2022 until 12/25/22. If an item you buy has a price reduction before Christmas, we will credit the difference upon request, so you can shop confidently knowing your price is guaranteed.
All credits will be issued as Loyalty Club Points on your Tower Hobbies account.
