Snapchat's unique selling point has always been the fact that images and videos could be shared with one other person before--poof!--they went up in smoke. Now, though, the app is branching out, to provide a 24-hour timeline to share with friends.
Same thing happened to me as Melissa. My bank statement showed a $20 charge for several days, however today (4 days after I used the facility) the $20 charge is now gone and it is corrected to the appropriate $5.75 charge. I don't know what happened, but I am happy it was corrected.
