Kirkland TP at Costco Great balance of price/quality.
Just gone through a package of Kirkland TP... complete garbage, it breaks apart easily and isn't very absorbent... you do get a lot though... I think it was 425 sheets per roll. Still, crappy TP is crappy TP. However, the Quilted Northern at Costco for $19.96 is a decent deal:
30 rolls x 267 sheets per roll = 8010 sheets. $19.96 / 8010 sheets =$0.00249189 per sheet.
OP's amazon deal:
48 rolls x 176 sheets per roll = 8448 sheets. $21.72 / 8448 sheets =$0.00257102 per sheet.
Costco regular price is cheaper than this Amazon deal.
Costco has $2 off Charmin this month so that may be cheaper... I use Quilted Northern so I don't know the price break out for the Charmin.
