It seems like Lulu always has a discount code. It stops feeling like a deal when I know that as soon as one “limited time offer” expires, there will be another to replace it. Instead, it makes me feel like their “regular” prices are artificially high. The “limited time offer” stops having the effect it was designed to create.
This isn’t something Lulu invented of course. e.g. There’s a local music store I stopped shopping at years ago for the same reason.
