Where to find her old concert DVDs?

[ILoveGeniuses]

I own EVERY Ayu concert that been released or re-released on the bluray format. However many of her much older concerts are still only on DVD and sadly I have none of the ones that are not available on the bluray format. I also cannot find most of these older DVD ONLY concerts. Is there anywhere online to find them that can be shipped to Canada?

If you are interested in buying physical DVD, than it's better to check yahoo auction from time to time. Buyee https://buyee.jp/ was a nice middleman service
