This offer is not available to everyone - most likely it works just if you never had Pets subscription order!
Amazon has Standard Dog Waste bags on sale today - 45% (5% regular subscription off, 40% off special today) off is you subscribe.
900 count comes to price:
21.47-1.07(5%) - 8.59 (40%) = 11.81$ + HST
This is the best price I have seen, even better than black friday deal price (around 16$ last year).
You can cancel subscription after you got your item.
Note - today amazon has "Save an extra 40% on your first Pets Subscribe & Save order. " - so the same 40% applies to any "Pets subscribe order", but just if you are eligible!
Reason: uncalled for
