That said...they are also extremely expensive.
For a slightly cheaper alternative, you can find strawberries imported from Japan that are probably 95% as good, albeit not as pretty looking. I've seen these going for about $30 for 10.
For a slightly more cheaper alternative, you can find strawberries imported from Korea that are probably about 90% as good, albeit not as pretty looking. These seem to go for about $15-20 for 10.
They're all significantly more expensive than the North American berries you find at the local supermarket, but they're also significantly better IMHO.
