I had experience with a custom store. Lucky me. It was good. What can I say... If you're new in drop shipping business (as was I) it'd be better to order a custom store. You'll chat with specialist, connect your wishes with reality and get a ready store. Actually, I didn't chat, I wrote the big list of questions and send it to my manager. He contacted me in 2 days with the detailed answers and counter questions. The process of approving my requirements took about 1,5 weeks, it was ok for me as I want a perfect made store. After discussing all requirements, my manager sent me some designs for approval and finally i got my store after 3-3,5 weeks. I can say it was good experience or may be and I had a good manager. However, do not afraid ask questions and give your requirements. Good luck with your business!
