how early to arrive for merchandise?

truroute

Hello all,

I won 11/29 Portland and 12/06 Seattle show tickets via Ten Club Drawing. Couldn't believe it when i did, my luck usually isn't that good. I'm stoked. Last time I saw PJ live was in Denver back in '06, which was where I found out that the unique show posters are a thing. (I snagged the PJ poster but not the PJ/Tom Petty one, bummer)

I'd like to get posters for these 2 shows also.

My question is: how early do I need to show up to ensure I get them before they sell out?

Thank you in advance for any information.
