Mega Building Supply - Upper West Side

This review collection mentions various positive experiences for a hardware and building supply store (likely indicating the business type, though the exact 'countertop supplier' nature isn't fully confirmed). Customers consistently praise the friendly, knowledgeable, and helpful staff (including several staff members praised by name, though one review recommends avoiding a specific person or type). The expanded location is noted by some. Pricing is frequently described as reasonable, convenient, fair, or inexpensive compared to other stores. The store has a 'no return' policy for certain items, which is a potential drawback. The store's closure on Saturday is acknowledged as a limitation.
