Self test covid kit

with this pandemic,i incur more expenses buying disposable 4 ply face masks,disposable gloves,hand sanitizers,and self test covid kit.i went to condo management office pay maintenance fees on monday and today saw office closed due to a staff covid positive.moh closed office for deep sanitization.i bought a few self test covid kits and do self test after i return home after shopping or hospital visits.lucky its negative but hope the kits are reliable n dont give false results.but i have no sore throat n cough so all should be ok.extra precautions buy more kits
