FROM A SELLERS POINT OF VIEW -
Generaly speaking, if someone pay's for an item quickly then i tend to leave feedback as soon as possible.
FROM A BUYERS POINT OF VIEW -
I only leave feedback when i recieve the item for 2 reasons,
1. It lets the buyer know you've recieved the item.
2.If there's a problem with the item e.g took longer to recieve then stated, product not what was described etc then you can state in your feedback to that person.
Unfortunatly some people are still confused about the importance of feedback, so here's my views -
1.If a seller has good feedback then your more likely to buy from him / her.
2.The higher the feedback the more likely your going to trust that person.
I personally hate people not leaving me feedback, especially when i've spent my hard earned money on there item's.
It takes a couple of second's todo it but makes a big differance.
