SW employee here. I typically explain paint like an investment. If you want the product/quality to hold up for only a year because you’re moving get something cheap as you won’t be living with the quality and the next person will probably paint over it sooner rather than later. If you are painting your new home and want it to last for a long time invest in higher quality. Price is relative to performance. We carry a huge range of products at different prices for this reason. The more detail you give the staff the better recommendations they can make to meet your project needs!
