Cheap luggage bags in Tokyo?

I intend to buy quite a lot of stuff in Tokyo next month so am thinking of getting a couple of cheap luggage bags, preferably hard case bags, to store my stuff. Would appreciate if anyone can point me to the right place, preferably in Ikebukuro. Used and even horrible looking ones are fine as I intend to dispose or give them away after I return home as I do not have the luxury of space. Thanks!

Try Don Quijote http://www.donki.com/search/shop_list_en.php?pref=13

Also heaps of choice at Ameyoko- just jump on Yamanote and get off at Ueno.

Thanks guys. Don Quixote looks promising.

Try "Ginza Karen's" You can look them up online too.

They are on the same street and a few stores away from the big 12 floor Uniqlo in Ginza.

Ueno/Ameyoko indeed is a good option. Just returned from another trip with way too many souvenirs, bought a pretty large backpack for only 980 yen here: http://goo.gl/maps/W4THq

They had hard case trolleys starting at I similar prices, I didn't look for bigger suitcases. And they definitely aren't the only place around, I only had limited time and this was simply a shop I already knew (don't ask...). But if you look further at Ameyoko, there are probably even better offers.

Another solution which I used for smaller but fragile souvenirs: just buy a couple of large plastic video cassette storage boxes at a 100 yen-store. That way I can travel with a large but light soft bag, and still get all the stuff back home undamaged.

Wow, looks like its gonna be Ameyoko for me now lol! Thanks guys!
