Snapchat is all about the dollars these days. The social messaging service recently made it possible to pay real world money to watch back messages that had expired and now they're reaching for your wallets again.
They've just launched a lens store which will allow users to pick up new effects they can add to their videos and images. 30 will be offered every day and once you buy them for 99 cents you get to keep the effect forever. There are also 7 free lenses everyday which appear on a rotating basis, so if theres one you really like and think you'll use a lot, being able to buy it for a small fee makes sense.
It's also a good way to give people a reason to check back in with the service on at least a daily basis to find out what new wierd effect has been added to the list. How impressed will your friends be if there's one which turns your face into that of an alien and beams you up into some kind of space travel ship? We really have no idea, the Snapchat generation is beyond our ability to understand.
The update to the app is rolling out now, so look forward to plenty of new looks in the Snapchats you're being sent soon.
