Here goes the quetion......
Xenon retails telecommunication appliances. In order to launch a new product, he advertised a Grand Summer sale in a local newspaper as follows:
‘Grand Summer Sale: Super Sellphones at Giveaway prices. To be sold only at $50 to the first 10 customers who reply enclosing a cheque for $50.’

The day after the advertisement had been published, Yoyo posted a letter to Xenon, enclosing $50 in cash.  Yoyo was one of the first 10 customers to respond to the advertisement. Meanwhile, Xenon had discovered that he was unable to obtain ten of the Super Sellphones because of a fire at his supplier’s warehouse. Accordingly Xenon published a further advertisement in the same newspaper for the following day announcing that the Grand Summer Sale was cancelled and that the special offer on Super Sellphones was no longer available. Two days later, Yoyo’s letter that had been delayed in the post, was delivered at Xenon’s address. Xenon now refuses to supply Yoyo with a Super Sellphone.

Now me as the plaintiff need to fight on this case and win it. I asked to use the contract law to win this case.Please help me.Thank You
