I've overstocked on generic pinch type lens caps and need to shift a lot - Due to postage costs (over £1 per order even in the UK) this only makes sense if buyers take several. So I'm offering batches in various sizes, price per batch is £2.50 or VERY near offer, P&P in the UK is £1.06 for 1 batch (large letter rate), £1.50 for 2 batches (large letter rate), then £3 for 3 or more (small parcel rate) 52mm - Batches of 5 - http://www.ebay.co.uk/itm/133290235921 58mm - Batches of 4 - http://www.ebay.co.uk/itm/133290238144 67mm - Batches of 4 - https://www.ebay.co.uk/itm/133290239157 77mm - Batches of 3 - http://www.ebay.co.uk/itm/133290241973 Due to postage costs they're probably not worth it if you're outside the UK unless you want much larger quantities: please contact me via eBay with the quantities you want and I'll weigh them and work out postage.
Update - all 52mm and 58mm now sold I've revised the 67mm and 77mm listings to sell any number of caps, eg just one if wanted, with cheaper postage - this is still a bit pricey for one cap, but comes down to approximately the same price as the original listings if you buy two or three more. URLs remain as above.
