I have been searching for Sony MP-CD1 since long online but did not find it anywhere. Purchased one earlier from Amazon but had to return it because of the product delivered was not carrying Indian invoice and MRP sticker. I ordered at this site with lot of hesitation but the offer was good. 5% Instant discount on my PNB credit card.
The product delivered well on time and packed neatly. All contents were intact and a valid Indian invoice. Thank you guys for the prompt delivery.
