If you want to shop local and help a local business then try The Eclectic Collection at 575 Garratt Lane (there seems to be a problem with their website at the moment). They double up as a really nice delicatessen and as a cafe, so are probably suffering from reduced footfall. They did a really good hamper for us earlier in the year, and we are planning to get them to do another for much the same reason as you.
PS - I've just worked out that their website is at
