Lastminute.com has signed a contract with American Express to offer exclusive late deals and offers to Amex cardholders.

The offers, ranging from extreme experiences such as learning to race a powerboat or taking a Tiger Moth flight, to booking holidays or concert tickets, are listed on a special American Express-lastminute.com co-branded website. American Express Green Charge Card holders can access the deals though Americanexpress.co.uk/green.

"This arrangement will enable us to offer some great and exclusive offers to American Express's high-spending, internet-savvy card members," said Martha Lane Fox, chief operating officer at lastminute.com.

Lastminute.com has been very aggressive on the deal front of late. Last week it announced a deal with Holiday Autos to provide a car rental service to its users, just two days after it said it had launched a catwalk fashion guide in partnership with inshop.co.uk. Despite the number of deals, investors were not entirely convinced and Lastminute.com's shares dropped 16.5p to 134.5p by the end of last week.

According to research by MMXI Europe, Lastminute.com is losing customers, dropping 22,000 unique users (to 711,000) between July and August.
