Magazine Subscription Delivery
The magazine subscriptions currently offered on TripleClicks.com can be shipped to any address within the 50 United States. At this time we are unable to send magazine subscriptions to other destinations outside the US. Once you've placed an order, it takes one to two weeks for your subscription to be received and scheduled by the publisher. Your subscription is then added to the publisher's next production cycle and shipped via standard mail. For example, if your monthly subscription was ordered and received by the publisher in November, and the December issue has already shipped, your order may be added to the January mailing.
The number of times your magazine subscription publishes each year will determine when you will receive your first issue. For example, the first issue of a weekly magazine should arrive within 4-6 weeks of your order. The first issue of a monthly magazine should arrive within 6-10 weeks. If you have not received your subscription within the expected time frame, please contact customer service. Rest assured, your subscription starts when you receive your first issue -- not when you place your order. If you subscribed for 12 issues, you will receive all 12. Some magazines are not published according to a regular schedule, nor can their publishers always promise in advance when the next issue will be available. Rest assured that if you place an order for such a magazine, you will receive new issues as soon as they are available.
