that was always one of the problems with deva products, you literally have to use a ton of them. i don't like the newer formulations so i've switched. i mostly use curl junkie, which seems like it is more expensive, but you use a small fraction of the amount of product.
also, both deva and curl junkie products are sold on they always have one or two coupon codes going. i think the current ones are
FIVE -- 15% any amount.
BEAUTY25 -- $25 off $100 & over.

shipping is always flat rate $5 for below $50, $1 for over. their turnaround is quick and their customer service is great.
