Great transaction

The comic was packed very well. The comic itself had a backboard that was the correct size and fit well inside the resealable bag. The box was made for comic books so it arrived in great shape. The deliver of the product was quick. Over all a great transaction on a comic book I needed for my collection. Thank you everyone at Alternate Worlds.

Best Wedding Gift

I bought this Skylanders piece as the centerpiece for best man speech in my brother's wedding. When we were younger I used to destroy all of his Skylanders, so in a week I will give it to him with much fanfare.
Thank you Alternate Worlds for giving me the chance to give him this awesome gift!

Awesome product, great seller

The Storytime Chess series has instilled a real love of chess in my 5-year old (and me)! The teaching techniques are great, the stories are cute, the degree of advancement between levels 1, 2, and 3 is appropriate. This is also a great seller, very responsive, courteous.
