Sa-kis now have an online store, which seems to stock all the excellent gear they sell in the street store. I've not had chance to purchase yet, but they seem to have a large selection of stuff available.
Free postage is a bonus too and apparently its next day - though again, I haven't yet tried it out.
Nice clean website and easy to find a specific brand etc. Takes paypal only at the moment, but ships worldwide. You don't need a paypal account to pay for things though. Not sure if they allow collection from the store, or if prices differ. read more
