Yeah, good luck with that. Palms don't lay every year, and I can't imagine why a breeder would sell an egg for less of a price than a weaned or nearly-weaned baby. There aren't many successful breeders of Palms, and most have waiting lists -- and many also require substantial deposits. With birds selling for over $10k, even a fertile egg would likely cost several thousand dollars. That's a lot to pay for something that stands a good chance of not even hatching after being shipped.
But, let's make believe you succeed in not only buying but also hatching an egg. Considering how much you'd be spending on that egg, I hope you have substantial experience hand-feeding day-1 baby parrots. Even then, Palms are finicky, requiring food different from your standard "baby parrot formula."
OK, let's make believe you succeed -- are you ready to spend more money for a cage? Palms have big beaks and are very active. A cage big and strong enough will likely cost another thousand or two. Toys will need to be replaced regularly as they are destroyed.
Thinking of this as an investment toward putting together a breeding pair? You'll be waiting a while -- most palms don't start to think about breeding until they're several years old (some not until they're in their teens or older). And in general, hand-reared males take the longest -- if they ever even want to breed. The palms which bred the youngest tended to have been parent-reared.
They're beautiful birds, and if given what they need can make spectacular companions or aviary birds, but trying to get yours as a fertile egg is the wrong (and exceedingly unlikely to be successful) way of doing it.
