Yes there are other types of promotional plans that may be available. These include split promotion and instalment interest bearing promotions:
Split Promotion
This is effectively a combination of the above promotional types. That is, you may make an Interest Free Payment Deferred purchase with the payments deferred for 6 months for example, after which you may have another 6 months where payments are required, but without interest being charged for the whole 12 month period.
Instalment interest bearing promotion
The benefit of this promotional type is that your repayments are spread over the promotional term into equal monthly instalments, including the interest component. The interest rate on instalments during the promotional period is at a special lower rate than the account rate. If there is a balance outstanding after the promotional period (eg. you have missed a payment for example), then interest is charged at the prevailing account rate.
