BCSE has done several custom modifications and installed everything from small custom mods to full X-carts for me over the past few years. They've always done a stellar job, with timely completions, very good communication and follow-up customer service.
Today I successfully installed one of their free mods that just happened to be what my customer was demanding today, reminding me to write this testimonial that's been on my to-do list for a long time.
I highly recommend them for their extensive experience with X-Cart and their wonderful, personal and professional service!
