No, customized t-shirts for your bachelorette party aren't very expensive. Remember to buy from the right t-shirt designing website to receive the best rates and high quality. Many websites out there offer you cheap customized t-shirts. But, the catch here is that the writing and images on these t-shirts don't last. You'll find them flaking off after just one or two uses. So, it makes more sense to spend a little more on a good quality customized t-shirt.
