There is an abundance of shops in Rishikesh, you will find anything from pharmacies, toiletries, Ayurvedic shops, clothing, and much more.
The main thing Rishikesh does not offer is some laptops and phones relating goods and services. For example, there is no service center for Apple products in Rishikesh however there is one in Dehradun. We would therefore advise you to bring extra cables and adaptors if possible to minimize time spent on replacing and fixing digital accessories. Anything from Pharmacies, to toiletries, ayurvedic shops, and clothing
