The versions that Chris and Jorge posted both seem to only imply that
the shopping is done on one day of the week, not that it is the SAME day
each week.  I see two ways

ro da poi jeftu de poi di poi djedi zo'u di mo'edemoi lo'e ze jefydje
zo'u mi tervecnu

which is explicit but incredibly hard to figure how to say on the fly
(not to mention that no one will remember that mo'e is the sumti to
number converter)

or the slightly elliptical but much shorter and clearer

roda poi jeftu mi tervecnu ca lo tu'omoi jefydje

If the hangup is whether something is a category of something or is the
thing itself, we have klesi and jutsi for defining subcategories, and
cmima among others for indicating membership within the category.
porsi may also fit in here somewhere.
