Which is better doing from below 2:
1) After a user clicked 'add to cart' for my product, should I redirect him to make payment first and then redirect to OTO1, OTO2 etc..?
2) After a user clicked 'add to cart' for my product, Can I redirect him to a Page OTO1, OTO2 etc. and at end he will make final purchase for all the added products in the basket.
