Agreed - DS is probably the most generous of any of them, but they still have a "process" you have to follow. Call in, get them to send you the form, answer a few minimal questions about your salon, send it back with your flyer, give them 2-3 weeks (sometimes faster) and a nice box of goodies will arrive.
ALSO - if you use images from DS (or Cal Tan or others - whoever your favorite is), most offer "
co-op advertising" credit, where you can submit the invoices from the advertising you do (a flyer, a postcard, a radio ad, etc) and they will give you a certain percentage back in $$ and/or lotions.
Again - a "process" you have to follow, but well worth taking the time and effort to do it!
