You might be wondering if it is really worthwhile buying online as there is the freight to consider. But don't forget that your bricks and mortar stores also have to pay freight on the parts they get - and they then pass that cost on to you, as well as their other overheads. By buying parts online you can often get steep discounts as online stores do not have to pay staff or rent for a shop front. And often they will give you free freight if the cost of your purchase is over a certain amount.
Tip 3: Always do this types of a shopping from some reputable site. This is because an established online store will always give you a guarantee on its products and services and has an access to all the top brands. So, it's better to go with the best option. Tip 4: Avail the services of only that store which has a return policy, in case your goods are not the one you ordered or are not working well. In this way you have a scope for an exchange or even return. Be fully informed and only then start your purchase.
