i live in lkwd shoprite in lkwd closed down but their is one in the next town of howell nj
the lkwd costco is full of frum people yet their kosher food products are sparse and they never increased the kosher food section
most frum will stock up on water, paper goods, spices over the counter meds but aside from 2 products from mealmart (large deli packages) and OU lox you,ll end up across the road at bingo or local lkwd kosher supermarkets
