In-Store Vs Online Prices

Why do some products have 2 different prices displayed, for in-store vs online purchases?

This is because it reflects certain benefits you will receive buying in store vs online. Those include having having expert advice at hand in our stores to ensure you purchase the right product for your needs. Our experts can assess your requirements, demonstrate products, and also you can try-before-you-buy. It also means we can set the product up for you and you can take the item home the same day. The aftercare received from your local store will also allow you to be worry-free. To this end, the warranty cover on in-store purchases is substantially more extensive than with online purchases.

In order for us to provide our customers with all the desirable features from our industry-leading stores we have additional costs that allow us to provide the service required. This is reflected in the difference of prices online vs in store. Most online products are also drop-shipped directly from the manufacturers as kerb side delivery so this will have to be unboxed and set up by the purchaser. Please contact us if you have any questions.

Why do some products have more than 2 different prices displayed, for in-store vs online purchases?

This is the case with variably-priced products. Prescriptive items in particular, e.g. powerchairs, have a base price which can vary greatly from the price with cost add-ons. For all variable products, the in-store price shown is the in-store price for the base model, i.e. the lowest-cost version of the product. Different configurations of a variable product can affect in-store prices, just as they do online. Please feel free to contact us if you have any further questions about this
