Tag Your BagIt doesn’t take much to make a difference.

That well-worn copy of Ivanhoe, last year’s holiday read, and that picture book on trains (which, let’s be honest, no one even remembers buying), are all gathering dust on your bookshelf. Bring them in to an Oxfam bookshop and, whether their collective sale totals £2, £10 or £50, you can be sure that you’ve directly contributed to the fight against global poverty.

But what if you could give more? You probably would, wouldn’t you? No, no, we’re not expecting you to part with that Beatrix Potter collection from childhood (heaven forbid!); just to help us get the most out of that which you do donate.

Oxfam have been running the unique Tag Your Bag scheme since March. The premise is simple: signing up to the scheme allows Oxfam to claim an extra 25% of the selling price of each donated item (thanks to Gift Aid), which means your donations are worth more, and as such are able to make an even bigger contribution to Oxfam’s work worldwide.

The good news for donors (besides knowing that the extra 25% is greatly appreciated by the recipients of aid in countries as diverse as Armenia, Bangladesh and Niger), is that the scheme now has links with Nectar. Each donor will receive 100 Nectar points upon joining the scheme, and an extra 2 points for every £1 raised thereafter.

Signing up is easy and can be done either in-store or online. Similarly, getting a Nectar card (if you don’t already have one) is a simple process and can be done relatively quickly online, after which you can start collecting points straight away.

It’s often easy to disregard just how important that 25% can be. But just think: the extra £5 received when someone buys that book on trains could pay for 24 buckets of clean drinking water for Malou village in South Sudan. Not bad for an extra 5 minutes’ work.
