Usually an Ancestry subscription costs the following for a 6 month subscription:
- Key Australia & UK Records - $99.99
- All Australia, NZ, UK & Ireland Records - $139.99
- Everything on Ancestry (Worldwide) - $169.99
But if you use the Gift Membership option you get the following prices:
- All Australia, NZ, UK & Ireland Records - $109.99 for 6 months or $199.99 for 12 months
- Everything on Ancestry (Worldwide) - $139.99 for 6 months or $239.99 for 12 months
You can send the gift subscription to yourself (so you don't need a second account) and you can choose when it starts as well.
Note: You're meant to get an email to confirm the subscription after your purchase, but when I tested this I didn't get one until the day I nominated the subscription to start and then I got two.
Also worth noting you can access most of Ancestry for free at a library, but for those that want a bit more this may be worth it.
All those 999s in the prices tell you their market research says their customers are stupid.
