Is it good to sell something at a low price just to establish a relationship?

i think it is not good because customer only depend on thier benifets.

we can define as 

customer can be two types

1.priece conscious 

2.qaulity conscious

3.third one made on nature base

if your customer is price concious you can make sale on both prices high or low on customer demand.quality known custmer not depend on price and not compromise on qaulity.other depend on your dealing and nagotiate process. you have to to face a trouble to convince this customer so you can make your on market by differing things from other.

china has to sale out it million of products on customer base areas it making thing in three types 

1.high price for high class.

2.medium price for mediam class

3.low price for low class 

this is its target market mathed.

it is my opinion if you want to promote your sale you can make or get medium price products with good qaulity.you can not face any loss and achieve a profit ratio.

if you promote your business you can make sale on low price at event based e.g eid crismas holi dewali and others which attract customer at you business place.

there is nothing as low price, each price define the product 

i can sell low price to establish a relationship with an offer on a product.

so, customer be happy

company not gonna loose anything
