However, we have competitively priced the product, so it only costs a little bit more than what some other vendors charge for their TextBox component alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 1,800+ components and frameworks for a subscription fee that starts at $395 per month for a team of 5 developers.
