06/08/15: We’ve currently removed a few shirt sizes from sale due to unexpected demand. For customers, certain shirt sizes will show the options as “currently unavailable.” By removing these t-shirts from sale we are able to fulfill the customer promise of shipping their orders on time. This also helps us to avoid extending the shipping date for all Merch by Amazon t-shirts.
We are working to restore these options to customers as soon as possible. Thank you for your patience and for being a part of our growing program.
We will post an update here once all t-shirt options are available for sale. We will monitor this thread to provide more information as we can.
