Hey there Rick,
Welcome to planDisney and thanks so much for your question! It looks like you'll be visiting the Disneyland Resort in a little over a month - how exciting! It'll be here before you know it.
I can definitely relate with your question. As a fellow "out-of-towner" from the Disneyland Resort, I'll be scrolling through social media or looking on the
Disney Parks Blog and see some of the coolest merchandise that is part of specific seasons, events, or celebrations at the Happiest Place on Earth and will really want to add it to the collection.
However, there is often quite a bit of merchandise that is only offered for purchase at the Disneyland Resort, but not available for purchase online.
If you haven't already, I would definitely recommend checking out the
Disney Store online to see if the sweater (or a similar one) that your wife is looking at is available there. If you don't have any luck with that, then make sure to check the
World of Disney store during your upcoming visit to see if it's potentially still available - though no guarantees there.
Sorry if that wasn't the answer you were hoping for, Rick, but I hope it was helpful either way! Thank you again for visiting planDisney and make sure to come back and see us if you have any other planning questions as you prepare for your upcoming trip.
Have a Magical Day,
Greg
