Yes, there is no reason why the buy no pay later scheme will work only for electrical appliances. They are available for all other types of items too. In fact, these schemes are now available for the smallest of items and range up to furniture, home items, etc as well.
You can visit different websites that sell the item you want and look for such schemes, there are good chances that you might find the suitable one for yourself soon.
For example, as we have mentioned above Open Pay provides installment payments for different items such as furniture, medics, and even auto-motives. So there is no limit and depends on the application/service you are choosing.
