Irishcoleen You could be right that receipt and checklist are not necessary, however step 4 in
"how to apply for an india visa from home" on the vfs web site (sorry can't post link) indicates you should enclose online receipt, and its no big deal to do so, also judsmiles had his application returned due to none payment even though he had payed online and it had shown that he had on his bank statement.
theres a guy who has some involvment with vfs in london on another forum who gives lots of advice, he maintains that applications made online are deleted after 15 days if they dont receive them in person or by post, they are still processed but in a different way so the online receipt could be important, again this happened to judsmiles and could explain why his application was returned.
