How to reduce shipping costs for low price item(free for buyer) ? What is best courier to use?

[hrm-pkr]

I need some help with shipping and postage cost and I apreciate if experienced seller give me some advice about postage and Shipping cost and what is best courier option, as it seems I am getting break even with my seling or if I increase the price,I won't sell.

The item I am selling(not on this account) have a very marginal profit and usually are bulky or better say bad shape/form but light weight. for example Two of my main selling products packaging details are :  (imagine flat piece of cardboards)

1-Width: 37 cm      Height: 1.8cm      Length: 68.5 cm       Weight: 0.875 kg

2-Width: 15.5 cm   Height: 4.5 cm     Length: 57.5 cm       Weight: 0.460 kg

Or some paper rools :

Width: 47.5 cm        Outside diameter: 7.25 cm        Inside diameter: 4cm           Area: 13.50 m²

the products are in low price range ( £6 to £10 ) and I usually buy them in bulk for half of the selling price , for Example I buy a £10 selling product for £4.89 etc.

My compatitor selling this for the same price, but I am not sure how they manage to do that,that is why I think maybe I am using the Wrong courier. We all source from same seller so We pay same amount to pay, but I cannot figure out how they manage to profit, when I struggle to break even. Now if I put the price up, of course I will not sell anymore.


Appreciate if you shed some light.

Thanks

Type "Setting Up your Postage Opticians" into Help and Contact at the top of the Page. There is a Link there to set a Business Seller Policy on Postage, Payments and Returns. As a Business Seller you will need to also add a 30 day Returns Policy to your Listings.

Thank you for the help, postage cost are very confusing.
It's very confusing. I have items selling on eBay for £3.5,I buy from retailer for £0.75.
it's only 80 grams but Problem is it's 3.2cm thick and I cannot send it using Royal mail Large letter format.
Bought only 500 of them ,but still just confused how other can manage to to post them with that price when lowest postage cost is £2.90 for small parcel. I guess there has to be something that I am not aware of !!!

I assume you are registered as a business on your other account, but you also need to do so for this one. A private account is for selling your own unwanted items, you are selling multiple new ones so are trading illegally.
