The better ones give you continuous email feedback, tracking numbers for the goods, a phone number you can call and an actual address where they are located. 70p for 100mg sildenafil is good. £1 is still reasonable. Probaby have to pay more if dealing with a UK-based 'broker.' Beware of scam reports based simply on big pharma -type police reports - almost always pointless. Even one bad review could be a competitor. But ones where several people have had money nicked obviously beware. I don't want to recommend the site I've used for all sorts of pharma, but Jimmy is happy to recommend.
