Sneda's website is a non-starter; it's just a page, which you can find here: http://www.localyte.com/attraction/20656--sneda-shopping-centre--Ghana--Greater%2BAccra--Accra. Conversely, Melcom's site promises to be big, but has not gone to be big yet. Here is the link: http://www.melcomgroup.com/melcom/html/index.html
These stores can be found all over the country, but, interestingly, never have I found the two so closely to each other. Sneda came first, but probably did not anticipate MELCOM's. Still the famed Spintex Road, from where I took this picture, offers significant potential for custom.
Four months after I took this picture, you should come and take a look at how they both have changed: SNEDA now has a clean, beige, minimalist look and feel at its entrance, whereas MELCOM is offering more competition by adding "MELCOM PLUS" to its regular store.
If you're ever in Ghana, or the capital--Accra--pass by and compare prices. If you don't like the quality, you know what you can do, don't you? Blog about it!!
Make your weekend nice and safe!
**correction: SNEDA is, in fact, Chinese. A facebook friend pointed it out to me. Don't get me started on the BRICs!;-)
