Yes, there is merchandise I started collecting this year and last christmas, and so far I only get new stuff around holidays and birthdays mostly (since we're pretty poor).
And if you need to know, the stuff i'm collecting right now is the manga :) Very small collection right now, I only own 3 books so far. I plan on buying my next book with my own money at the mall probably, so I may get it around november. Or sooner, as I duno when i'll be at the mall overall (movie lineup or otherwise o.o). 3 months is kinda a wait....xD Thankfully, pokemon manga is pretty fun to re-read! My first one, which I got last year (FOR christmas~), I re-read it 8 times now and still haven't tired of it :D Also, I like that manga books cost like 5 dollars now (sometimes cheeper)
I still find it odd I owned like no manga (cept one i gave to this mean girl i knew irl as a teen...) all the 16 years i've been a pokemon fan. But, hey, its never too late to start collecting if you plan on being a pokemon fan for the rest of your life, ammirite? :P
EDIT: I own so far....(bought in the following order :P)
1. Pokemon Adventures Black and White Volume One (read it 8 times!!!!!!),
2. Pokemon Adventures Ruby and Sapphire, i think volume 4? I read it twice so far :P And got it at the beginning of this summer.,
and,
3. Pokemon Adventures Best Of: Yellow (one of my birthday gifts this year and i haven't finished it yet).
Can't wait to see what my 4th book will be, lol :3
