Customer Reviews
Consistent quality over time
I've bought from Grand Slam New York a few times now, mainly for their MLB gear. This time I picked up a New York Mets Jersey. It was the same good quality I've come to expect, officially licensed and true to size. Shipping was standard, around a week to get to me, which is consistent with my past orders. I didn't need customer service this time, but they were helpful on a previous return. Their stuff always comes well-packaged, so no complaints about damaged items. They're a solid choice for NYC sports merch.
Quick shipping, nice mug
I ordered an I Love NY Mug for my sister. It came pretty fast, like 4 days to get here. The mug was wrapped good and looked just like the picture. Satisfied with it.
Good quality, fast shipping
I got a New York Yankees Hat and it came quicker than I thought, took about 5 days to reach Denver. The hat is officially licensed, felt really good quality, definitely not some cheap knock-off. The whole ordering process was smooth, no weird glitches or anything. It was packed well too, so it arrived in perfect shape. I'd order from them again.

Share tips, ask questions & help fellow shoppers save more
hey, was thinking of grabbing like 5 'i love ny' hoodies for my family. do they do bulk discounts or free shipping for a bigger order like that?
Are the yankees jerseys on the site the real deal? Or like, knockoffs? Want to make sure it's official before I buy one as a gift.
