they are totally two different places for me. i dont shop at whole foods normally, cause it isnt close, i try to go to new seasons, which is a grocery store here that has local and organic stuff. but anyways. its comparable to WF.
trader joes is good for super cheap luna bars, wine, beer and snacky type stuff. jarred pasta sauce, etc. the thing is though you still have to watch their stuff for hfcs and pho's and stuff. but its good to go there if you are going to have people over.
we get a produce box, but for bulk items, any other produce or dairy we need, i usually go to new seasons. also, supplements. i don't feel good about tj's supplements but i am not sure why.
