I've used Le Prevo for a number of years and, as everybody else has said, their online ordering system is rubbish! I still use them as they have always treated me with courtesy and professionalism. When I've ordered stuff that's out of stock, I've received a phone call from them to tell me and then we've discussed alternatives, the end result is nearly always that I receive a better product than the one originally ordered at the same price!
I'll continue to use Le Prevo as I've learnt to work within their system and now order with plenty of time to spare, so that I don't get stuck without supplies, and always phone my card details through on receipt of the 'gissyermonee' e-mail!
They really do need to drag themselves into the 21st century, but personally, they have something of an anachronistic charm linking the whole process to a time when the world had more time for everything. By now you've probably worked out that I'm old enough to remember when muffin the mule was an enjoyable 15 minutes on a small black and white telly rather than its latest incarnation as a line of rubbish innuendo!
Right, I've built a small pile of bails to hide behind so I'll shut up now!
But, I will continue to buy from Le Prevo as they're the cheapest around if you can live with customer service from the 40's!
