take advantage of swap meets, flea markets and farmers markets. we stopped by this afternoon and found poblano chile for less than $1 per pound.....cheaper than the grocery store.
if you are looking for a specific tool you will be in luck. yes, they are used, but they always get dirty anyway.
there are many other items at significantly discounted prices such as toiletries, kids toys, costume jewelry, jewelry repair, watch batteries.
the battery in my honda key is dying which would likely cost no less than $50 at the dealership to have replaced. we got a quote at the swap meet for $6.
