I LOVE Method detergent! It gets stuff clean, it smells nice, and the new pumps are sooooo easy to use. But it won't trim your budget - Tide if definitely cheaper. If you are looking for a long-lasting, inexpensive, non-petroleum-based laundry detergent, I suggest you check out Charlie's Soap. You can find it on Amazon.com for free shipping, and it lasts forever because it is super-super concentrated (I'm not sure how much, but you use 1 Tbsp per load of laundry and it comes in a huge bottle, so after over a month, I've hardly made a dent in it). But it doesn't really smell at all (which could be good - no perfumes), and can be hard to find locally. Good luck!
