<human>:  How can I best save money on groceries?
<bot>: One of the best ways to save money on groceries is to make a comprehensive grocery list and stick to it when shopping. Planning meals ahead of time, buying in bulk, using coupons, and price-matching are all ways to get the best deal. Shopping at discount stores and farmers' markets can also help lower costs. Finally, try buying non-perishable items online, which can often be cheaper than in-store purchases.
