Answer:
I took inspiration from the answer above me and reworded it and made it slightly lengthier. Almost all credit goes to them.
Its best to plan to get a good or service that is very beneficial in many ways, or it can be used/owned for a decent amount of time for the price that you're paying. You should always think about the quality of the object before buying it, and also looking over reviews from other consumers if there are any. If an object or service has no customer reviews shown, think it through and ask yourself if it's really worth taking the risk and being the "first" consumer of the product. You also want a good bargain, if a product looks like a great deal for its price, think it through, and if you decide you really want it, and you think that you'll have no regrets, then go for it.
For me, I used this answer and got a 100% for a journal activity on Edg.
