Home & Garden Construction/hardware materials free delivery

In another thread, I had posted that there are several construction/hardware stores in Dumaguete, such as -- Blas Elnar & Co (Locsin St cor Ma Cristina St, Brgy Poblacion 3), Citi Hardware (Perdices St, Brgy Calindagan), Dgte YY Trading (Pinili cor Real St, Brgy Poblacion 3), Duplamilco (South National Highway, Brgy Mangnao), Golden Rule Store (Ma Cristina St, Brgy Poblacion 3), Negros Building Supplies Depot (South National Highway, Brgy Tabuc-Tubig), Rejoice Hardware (Cervantes St, Brgy Poblacion 3), Robinson's Builders Main (Perdices St, Brgy Calindagan), Robinson's Builders II (North National Highways, Brgy Daro), Triumph Home Depot (Sibulan) and Uymatiao Trading Corp. (Perdices St cor Locsin St. Brgy Poblacion 4). Most of these promptly respond to email request for prices as long as requesting canvasser makes his materials list specific in size and make; but then, again, no store carries all needs.

While following up cost estimates this morning, someone mentioned that Duplamilco delivers free to home or project site, for minimum purchase of PhP1000. Please share if you know of other such stores that also deliver for free and for how much minimum purchase?
