Hello Venkat,
Thank you for your question about the payment plans. We added a free 3-second snipe to your account. There is no need to pay us if you just want to use it one time.
The reason the pay-per-use snipes are priced higher is because they never expire, so a casual buyer can use the account all year. The monthly plan only lasts for as long as its purchase time (month, year, and so on).
Good luck on your snipe! Let us know if we can help with any other questions.
