Everyone loves to get free stuff, so when you see, for example, your favourite make-up line having a gift with purchase (GWP), of course you're going to check it out, but should you get it? To see if it is really worth your money, first ask yourself some questions. 1) Do you need to buy anything? Sure, you might be able to rationalize that you will eventually need some cleanser, moisturizer, etc. but if I don't need anything at the time I don't get it, that simple. 2) Does what you need to buy add up to how much you need to spend to get the GWP? There is always a certain amount that you need to spend to get it, and one item doesn't always get you there. However, two items could end up being alot more. 3) Will you use most of the items in the GWP? Sure, that shade of lipstick looks nice, but will it suit your colouring? And yes, everyone needs a moisturizer, but is that particular one good for your skin type? If you're not going to use almost all of the items, keep your money. So, while everyone likes free stuff, always consider these questions. You could end up saving yourself money in the long run, something else everyone likes.
