you can get a custom Swisher jersey there.

$189 for this one. The cheap one costs $99.

They also have them on E-Bay for $75-85 plus $10 shipping.
I guess you are looking for a brick and mortar store? Have you tried the calling the Oakland Coliseum shop or is that all Raiders gear right now?

To add on, I am in the same situation as you maybe:
I am going to be in Modesto next week and was wondering if anyone knows a good place to get A's stuff, memorabilia and clothes in the Modesto/Turlock/Stockton area.

Also a good place in the East Bay?

I know I can order online from e-bay, MLB etc but I would like to go to an actual brick and mortar store and pick out some Christmas gifts this time around.

Thanks in advance.

for most players it's a custom job -- meaning it's going to be a big challenge to find someone to do it over the next week.

You could always buy the jersey now -- available at the Coliseum store and probably at sporting apparel stores in most malls and then have the number/name added later. That's probably your best bet.

I wanna get my roommate a Swisher t-shirt-- can I go to the A's store at the stadium? Is it open?

Thanks a bunch!

at this late a date before x-mas this is the route to go:

The above is not in the budget but it would be damn sweet to have.

They are a good place to go with cheaper prices than MLB.com and a more open view of what jerseys they can make for you.

MLB official jerseys run in standard sizes.  You could go to the Giants dugout store and just try on their jerseys to see what size of A's jersey you might need to order for your friend.  But it would definitely not arrive in time for Christmas.
