I discovered that the post office messed up and didn't notify me that I got a package waiting after a failed delivery (I only learned of it because I mailed HalfmoonBay asking them what the estimated shipping time was.
When I had gotten the package and opened it, I was more than surprised. Halfmoonbay sent me the following items:
Warhammer Age of Sigmar Pencil Case - Stormcast Eternal £17:99
Warhammer 40,000 A5 Notebook - Space Marine £11.99
Warhammer Age of Sigmar Bottle Opener - Stormcast Eternal £14.99
Warhammer 40,000 Shaped Mug - Space Marine £13.99
Warhammer 40,000 Wash Bag - Space Marine £19.99
Warhammer
40K Tin Sign - Space Marine £3.99
Im very pleased with how they handled this, like total bosses!
