I was going to post this in the morning after I had checked their prices, last sale was not as good as it seemed so don't just assume its a good offer, check elsewhere and make sure. Hertz have a 33% off(plus Quidco) sale running which might be good for some.
I have used Holiday Autos more than any other company over the past few years, they have just been bought out by CarTrawler. Their paperwork/voucher is not very good, collected car a couple of weeks ago and the Alamo agent would not accept I had paid for Gold. She eventually waived fee for additional driver but would not accept I had prepaid for one.
