TIP! Dell Discount codes available (up to 10%) Via Bigpond membership
I have taken a look though the Bigpond site and it would seem that if you joined their Casual Usage Plan for dialup modems @ $25 you are able to use the coupons on Dells site. At least I cant find anything in their terms and conditions specifically stopping you from using the coupons with this plan, it also seems that Dell dont run a check on internet orders to see if you are a member and if so which plan you are on anyway.
So if you are thinking of a dell purchase it may be a good move to join Bigpond on the cheapest package (Casual Usage Plan for dialup) and use the coupons with your online purchases.
