We're in Oz, so have been lucky enough to have been watching it for several years. DCs (6 and 8) still love it, and DH and I watch (and re-watch) episodes after they are in bed.
Favourite episodes are At the Pool (sooo true), Cinema and Hammerbarn (which is based on an actual hardware chain called Bunnings - even the staff uniforms, sign fonts, etc are identical - for real life!)
So, good news - I am sure you will get STACKS of merc to spend your dollarbucks on soon, because you can't move for it in the shops here. If you want to get some ideas, just google any Aussie stores (Big W, Myer, Target, Kmart - make sure it's the Australian versions though, not the US ones).
Also, all episodes are available on the abc's iview site. It's free in Australia, but I understand that it is also available overseas via App Store or Google Play.
Finally, just to mention, in case anyone didn't know - Bluey and Bingo are both girl dogs! The assumption always seems to be that Bluey is a boy, but I think it's great to finally have a show for everyone (boys and girls) with two sisters as the main characters.
