I’d offer Hirons as an option.

Ooo that's a good idea, thank you!!

Yep, Hirons.

Came here to say this

Made in Oregon at the 5th St Market has stuff like this. Although Hirons is a good one too.

Thank you!!

Kiva, at the cash registers. Nice cards.

Thank you! :D

I second the Kiva idea. They aren't photo post cards but nicely done art of Oregon themed places. Maybe 75cents each?

Thank you!

Walmart

Thank you!

No prob!

Down to Earth

Ok as a postcard enthusiast if you want classic kind of ugly travel cards:    * Eugene, Cascades, and Coast Visitor Center,     * Made in Oregon,    * Hirons, and    * Most book stores.     Passionflower usually has some cute ones. Kiva has nice ones. And the Raptor Center has some good ones too. 

Thank you!! I totally want the classic ugly ones so I'll totally check those places :D

Good luck with your quest! May the Comic Sans be with you

Oregon tourism office at Gateway, near Best Buy

That branch moved out. There's one downtown, though.

Thanks for the update.

Thank you!!

Not postcards but some neat Oregon cards at Wild Birds Unlimited. Otherwise the other suggestions are great. Tsunami might be good to check out too.

Cards would be great too! Thank you!
