Eagle-eyed STOMPer vanillaaijs spotted weekly charges totalling $320 hidden in the fine print on these flyers he received when buying local magazines.

Here's what the STOMPer wrote in an email today (Dec 3):

"I got these three identical 'winning cards' from 8 Days, I-Weekly and U Magazine.

"It says that the SMS to claim the promotion is charged at a standard rate.

"When you read through the fine print however, you will find that you are actually subscribed to a $10 per week service from TXT MOBI, and that the drawing date is June next year.

"This seems like a trick to get people to join and unknowingly pay $40 a month for these 'services' until next year, if you do not read the fine print carefully.

"This is very similar to the recent case in the news about a teenager who spent nearly $1700 to take part in an SMS competition.

"$40 x 8 = $320 if you are not aware of the cost."
