Hi Kate,
Argos is one of the biggest chain-shop in England. You can rely on them for shopping anything found in their cart. You may shop and pay online for a home delivery (if applicable) or place an order online to reserve for pick-up from your nearest Argos store or you can personally visit any Argos store, make a choice and just pay over the counter.
If you want to shop online, I suggest, not to hurry and check if there are any sign like 'cross', ' * ' or some other kind. It means, the product has some conditions to check properly.
There are many promotions may be found to avail. Check that out.
Best of luck.
I'm Kate (not middleton) from Barnsley, Yorkshire. Want to buy a new mobile, probably some android operated cool smartphone within my budget. I heard that Argos has a very rich and comparatively cheap priced mobiles. I have no idea about Argos. Do you have any practical experience shopping from them? Was it good enough to share? Do they really sell cheap mobiles or just fumbling? How do I make payments from here? Please advise.
