with their coupon . Could possibly use a member card from someone you know or they have a 60 day free trial membership which gives you the full discounts . Here it is http://www.bjs.com/biz/minisite_map/images/pass.gif . The conventional is 12 quarts at $34.99 -$9.00 = $25.99 ( $2.17 a qt. ) and the synthetic is 6 quarts for $27.99 - $9.00 = $18.99 ( $3.17 a qt. ) . They usually have 5w-20 > 10w-30 .
