Where to buy cheap walnuts in Bulk

[Ceviche]

Its 1 block away from the Olleros stop on the D line. 1 block south, right next door to Coto. I don't have the per kilo prices right now, and won't be going there till early next week, but I can at least say it fits my (very meagre) budget.

Thanks @ Ed Rooney. I was able to reach there.

I bought 5 Kgs of best walnuts ( without shells) for 320 pesos. Original price was 9.99 pesos/100 gms
